Yes it is a heavy lens. Should it be not heavy For lightness I use other cameras. Build quality is very good.I use it on Nikon D810. Very sharp and fast autofocus. Manual focus is precise and comfortable. You will not regret it.I love it. Highly recommended.
Hilmi –
But who cares.Sharp from edge to edge. I own also a zeiss 50 mm 1.4. I love it so much but this is better. From art perspective and from light transparency. Autofocus is very very quick and nearly no miss in five days experience with my d810. I am sure all of you are waiting for dxo results etc to decide between tokina opera or cheaper 50 mm art but Let me remind you this is also for 8K video. It has future.
DAVID –
The good1 Sharp, like my camera suddenly got 5 more mega pixels.2 just as accurate focus as native glass, far better than the other half dozen sigma art lenses I own.3 auto focus is fast enough for portrait work4 weather sealing5 on my apsc cameras this is a 65mm lens, which is a great angle of view for portraits.The bad1 its heavy2 no ISOS, which is like almost every other prime. Canon, wheres the IBIS

This lens design has the potential to be among the extremely few designs shorter than 85mm capable of the superb optical performance, i.e. corner to corner excellent detail on a plane at infinity at f2.8, which photography of starry skies often demands, especially for astrolandscape, as opposed to pure astro work where no land is in the image and longer lenses are employed, on average, and everything is done on an equatorial mountclock drive. For that kind of work, f4 is more commonly used and works out pretty well with some of the best lenses, though sometimes 5.6 is used as well, at least thats my sense. For astro landscape, even larger apertures like 2.0 and bigger are often used, though not without further sacrifice. Equatorial mounts are of great usefulness for astrolandscape as well, if you want to get anywhere near to the best possible results. Apart from lens design, the assembly of the lens plays a huge part in the resulting quality, but so does the cameras sensor to lens mount alignment. Unfortunately the Sony Alpha sensors are relatively poorly aligned, on average, if my sample of four A7r IIs is any indication, not to mention the inherently inferior method of Sonys sensor alignment, using shims which come in fixed 50 micron increments. An error in a teardown article suggested it was 5 microns it isnt. It looks as though Sony cannot, given this method, individually adjust cameras the way Canon can, by using their springtensioned screw design, on the assembly line. The four A7r IIs that I and a colleague very carefully measured were out of alignment by between 30 and almost 50 microns. The one EOS, a 5D II, which I measured, was off by about 6 microns. Under 10 to 12 microns is pretty tolerable for this insanely demanding optical problem, but 6 is highly desirable. After months of hassle I was able to adjust my own A7r II to within 10 microns by shimming the lens mount ring. Long story. But on that account, and on account of the performance of several other lenses which I own, and my own system for measuring camera sensor to mount alignment, I was able to confidently conclude that the focus tilt I saw in three copies of the Sigma 40 ART was a defect of the lens in by far the greatest part, or rather of the calibration of the lens which is likely done with shims under its rear mounting ring, and not a defect of the Sonys sensor alignment, except to a small degree. The best of three samples, which were otherwise superb, focussed at about 80 feet in the top right, while focussing at about 130 feet at the lower middle edge, which is a 25 micron error and more than can be overcome by best possible compromise focussing at f2.8, if stars are to appear to be in focus. F4 might work with that copy. Given tight calibration of this issue, these lenses would work at f2.0 and even wide open, though certainly not as well and with too much falloff wide open. The worst of the three had perhaps twice that tilt error, roughly.I checked to see whether the sheer weight of this lens on the Sonys lens mount ring was changing the focus and it was not. I could see zero difference in focus by pressing upward on the front end of the lens. Also if it had been, it would have been causing the opposite tilt problem. Some people allege that copies of Sigma lenses purchased in Japan are great, and that they suspect that cherry picking is being done in that way. My limited sample of having tested only four copies of two types, total, is far too small to tell, but what Ive seen at least doesnt contradict that possibility, as the sample variation problem in each of those four lenses has been larger than the fundamental optics problems which Sigma has successfully overcome, and to an increasing degree over time. My sense of the one Sigma 50 ART which I examined was that had it been a good copy, it would have been usable for stars at f4. Pretty good, but not good enough, still. For a million other uses, no problem, but for stars, most of the time, forget it. 2.8 or bust.When the Sigma 40s were refocussed, each part of each copy produced a superb image, including with point light sources bright city lights at over 10 miles or bright stars, not having more than a very little bit of the usual batwings, spaceships, angels and other shapes caused by the various aberrations which lenses exhibit to varying degree around their periphery and which are routinely referred to as coma in reviews. This is extraordinary and a sign of a superb design. I could see none of the focus shift when stopping down from 1.4 to 2.0 or 2.8 which others have alleged, so it was at least very small, and the curvature of field was fairly small though certainly visible, and seemingly smaller than the tilted focus problem. Why bother to make the lens capable of superb detail at 1.4 or 2.0 or 2.8 yet not capable of being in focus on a plane at 2.8 If all you want is infocus eyes in a portrait, thats easy for lens designers, though not for AF system designers. Perhaps its just too hard.Given that Sigmas entire push into very fast lenses was in part motivated by inspiration from within the company to make lenses for this very purpose, its puzzling to me why such a relatively easytofix kind of flaw would be allowed to spoil an otherwise stunning performance. It could be that looking at more copies would lead to finding one which happens to be right, but for now Im going to put on hold my search for a 35 or 40mm lens to use for stitching starry skies, as no clear candidates seem to exist. This after my colleague and I have examined, either in person or by studying reviews and samples, essentially every such lens on the market. The vaunted EOS 35 f1.4L II required nine copies for a colleague and I to find one marginally usable copy, mostly on account of strong field curvature. The three copies that I examined would require stopping down to f6.8 to become usable, making them a total waste of time, despite this lens being widely regarded as greatly superior to the 35 ART, for example. And so on. I hope Sigma ups its QC game further because I really like what theyre trying to do. The same goes for Sony and the Alpha fullframe bodies. They really need to switch to Canons system, even if it means making the body a few mm thicker, where each body is quickly and easily calibrated on the assembly line to within something like 6 microns using three springtensioned screws and a scanning laser micrometer setup to give instant, realtime feedback on the sensor position. 100 microns is the thickness of a typical sheet of laser paper The requirements are ridiculously tight for this kind of work, much more so than what is implied by the night sky work that we see online, usually at very low resolutions, almost all of which is a mess when you get to see it at 100, from both lens and camera optical limitations and noise issues as well. If you want to see what can be achieved, look at what the pure astrophotography photographers manage. Its pretty often seemingly flawless, though it usually involves a huge and complex effort to make a great portrait of a given nebula, for example.

Its a real challenge to take full advantage of its optical excellence. For maximum acuity on either my Z7 or my D850 I had to mount it on a tripod, manually focus on live view, delay the shutter 3 seconds and be sure there was no wind. Doing this gives me technically spectacular results. My copy does have quite noticeable focus shift when changing f stops.A more casual approach using auto focus yields nice result but not spectacular ones.And yes…the thing weighs a ton.

Dieser Objektiv wrde 5 sterne bekommen wenn es nicht so Schwer und nicht so teuer wre. Klar ist es scharf und AF geht viel besser als bei z.B 50mm.Ich glaube mann muss es zu erst anprobieren um Unterschiede zu merken.

This 40mm Art is not like other art lenses which are already great. in sharpness is outperforms its 85mm 1.4 art brother. also outperforms zeiss batis and zeiss otus…In fact it is a Cine grade lens in consumer category. Been comparing it with 70200 IS2 and 85mm art i can say that it is a hidden gemif you are oversmart you can check my findings from the findings of digital picturehttpswww.thedigitalpicture.comReviewsISO12233SampleCrops.aspxLens1392Camera979Sample0FLI0API4LensComp1072CameraComp979SampleComp0FLIComp1APIComp0

Summary A beast of a lens, with image quality to match. You get what you pay for literally.The goodImage quality is fantastic. Some of Sigmas Art lenses are amazing, some are normal, and some dont seem to cut it, even though the all get the mark. This one is one of the best.Natural looking blur past f2. At the minimum f1.4, the blur starts looking exaggerated like most lenses at that aperture, but some people like that. Past f4, blur is only on the edges and details in the autofocus zone are crystal clear.Quick AF Sigmas agreement with Sony on the Emount specs is paying off. However, if you like or want to manual focus, the focus ring is large and easy for your fingers to find.In addition to the solid Sigma Global Vision construction, actually feels weather sealed. There doesnt seem to be any openings to the environment.The badHeavy. This is not a mirrorless lens. This is a beast lens not for the faint of heart. You know just by picking it up that there is serious glass in there. It doesnt balance well if you like holding the camera by the body.Long. This was used on a A7R3. Because of the Emount neck, its longer than for instance a Canon version. However, if you like to handhold the camera by the lens like I do, it fits fine.The other stuffThis 40mm was supposedly built from the cinema version, but there arent any cinematype features at all. For instance, the Sony 135mm GM has an iris ring that can be declicked like that on a cinema lens. The Sigma appears no different than any other Art lens in that respect.
Mikhail –
I have the 35 and the 50 art, and friends have let me borrow other art lenses. This lens is better than all of them. It is Zeiss like in quality, and it is unlikely you will find a sharper lens. In addition, bokeh seems to be very nice, and the lens has a pop often associated with Zeiss lenses. The downside of course is the size and weight. It is big, it is heavy, but there is really nothing better, and so you have a choice to make. If you want the best, you will have to deal with the size and weight. The odd focal length is fine for me, yet I understand 40mm might be strange for others.

I have been using sigma 35 mm f1.4, I have decided to change with 40 mm sigma lens. This is amazing, ultra sharp and color contrast perfect,
Joe –
I own most of the Sigma Art prime lenses. When I buy a new lens, I test it for sharpness using a test chart. The Nikon D850 camera body is theoretically capable of resolving about 115 lines per mm lpm. Having already owned the Sigma 35mm and 55mm Art lenses, I questioned my need for a 40mm lens. But after seeing Sigmas published MTF curves, which appear better than those of the other 2 lenses, I bought the 40mm lens, and Im glad I did. My lens resolution target goes from 100 lpm to 120 lpm. so 100 lpm is my limit for the D850. At f1.4, my Sigma 40mm Art lens resolved 90 lpm center, 90 edge, and 80 corner. At f2.8, it resolved 100 lpm center, 100 edge, and 90 corner, an amazing result. Because the depth of field at these wide apertures is so shallow, I found critical focus with the D850 is best done by manually focusing in Live View with an external magnifier in order to obtain the peak maximum of resolution. This applies to even after adjusting the AFFT with the Sigma dock. Chromatic abberation and distortion are also extremely wellcontrolled with this lens. My only negative is that, for a 40mm lens, it is big and heavy. It would be nice if Sigma would come out with Art quality lenses at smaller apertures to reduce their size and weight. I have found this 40mm lens to be comparable in sharpness to the 55mm Zeiss Otis lens, but the Otis lens is manual focus and I will be able to use this Sigma lens for focus stacking with the D850.
Luis –
No 40mm can touch the performance of this lens…simple as that. Check the lensrenal tests for example. The resolution numbers from center to edge are stunning. This is as good as it gets.Yet it is big but with this performance, you cannot argue with it.
William –
I must admit I was impressed by the reviews and opinions I have read about this lens. All I can say is that it might be even better. Wide open at f1.4 it is sharp corner to corner. Backgrounds are outstanding for a 40mm lens. It is truly a multiuse top notch lens for both wide apertures and landscape apertures. The weight could be a problem for some, but very manageable I would think for most. On my DSLRs it needed a general same sigma dock adjustment at all distances. With the adjustment all results were stellar with minor in camera adjustments on my D850 and no adjustment on my D810 and D5. Results are also stellar on my Z6 with the FTZ adapter, and as good as the Z 50mm 1.8 lens is, the sigma has much better backgrounds with comparable or better sharpness, and of course more weight. Stellar image quality still comes at a price. Overall highly recommended
David –
Phenomenal sharpness and great colors across the frame. Autofocus is fast enough, and bokeh is beautiful. Heavy for the focal length, but the results are worth it. 40mm can work like both 35mm and 50mm, a really convenient length for general use.
John –
This is both the sharpest and heaviest pound for pound lens Ive ever used. I dont want to shoot with anything else. Odd focal length but starting to love it, especially when I know Im getting the best results from it. It is ungodly big and heavy though.
Sevan –
This lens is truly stunning and is one of the sharpest lenses you can ever put on your DSLR. I own the sigma 35 1.4 art since it came out along with the Tamron SP 35 1.8 VC. Both come nowhere near the wide open performance of this sigma 40 1.4. If I want the wide open infinity or even close focus performance of the sigma 40mm on the Tamron or sigma 35 I would have to use F5.6 to get what the sigma 40 does at 1.4. Just leaves your jaws wide open with what optical performance is achieved by Sigma.Autofocus is VERY silent, really fast and accurate on my D810. The sigma 40mm did not need any adjustments with the sigma usb dock that I needed to do for my 35mm so that is really great.Chromatic aberrations are virtually nonexistent. My wide open shot in sample displays this. Look at the leaves and lines along the building during a bright sunny day. Amazing performance Coma performance is great as well from what Ive read about even though I rarely shoot the night sky. As far as flaresghosting I have not tested it but according to lens tip review website this was one category it did not score very well due to having so many glass elements. There is also the slight issue of spherical aberration but honestly in my times of testing it and shooting at F1.4 to mainly F8 I did not experience any issues that would be a deal breaker. No lens will ever be perfect. Every optical designer needs to choose what to correct forSigma really cooked up something spectacular here. You will NOT be disappointed. I got this lens when it was on sale for one day at 999 so it was a really great deal at that time. I have attached a few sample images taken with the sigma 40. These images have mainly only the lens profile attached in light room and all are shot at F1.4.
Jimmy –
The weight worthy for the quality Images this lens produce.So very SHARP With beautiful bokeh. I pair with Nikon D850.
Ramachandra –
I use this on my Sony A7iii with the MC11 adapter. The lens is too big and heavy, but I knew that going in.Once you accept the sizeweight, this is an incredible lens. I love this focal length to cover indoor events. Focus is resoanably fast but accurate. Images are sharp and contrasy. The last few events I have used OOC jpgs even though I also shot in RAW the images were that good in jpg.I mostly shoot wide open indoors and the subject separation is very good.Overall, a fantastic lens. Highly recommended.
vincentmanuel –
I had heard good things about the Sigma 40mm, with the only negative being that the lens is large and heavy. This lens is a statement lens, and statement lenses typically have a clear goal in mind to be among the best in image quality and resolution. In that regard this lens does not disappoint, as the sharpness is phenomenal from cornertocorner. If you want a statement lens, and can accept the cons that come with statement lenses, then this lens is for you. If you love to pixelpeep, and crave high resolution, then you should consider this lens.

I own several Sigma Art, Sport and Contemporary lenses, so it wasnt a great leap for me to buy the Sigma 40mm f1.4 DG HSM Art Lens. Yes, its heavier than the Nikon AFS Nikkor 35mm f1.8 G ED lens that I used as a partial trade for this lens. But, I REALLY like a sharp lens, and while the Nikon was a nice lens, I wanted something better. And, even though Im 73 years old, I dont mind the heft of my Sigma lenses. I think too much is made out of lugging around an extra pound or so. Although, I did buy the Cotton Carrier CCS G3 Harness1, which I also love. The hardest decision for me was did I go for the Sigma 35mm f1.4 Art the Sigma 50mm 1.4 Art or the 40mm I already have the Sigma 1424mm 1.4 Art, the Sigma 24105mm f4 Art, the Sigma 50100mm f1.8 Art, the Sigma 85mm f1.4 Art, the Sigma 70200mm f2.8 Sport and the Sigma 100400mm f56.3 Contemporary, so my thinking was a combination of thinking that the 40mm would fill a hole that I wanted to fill, AND I knew that my fetish with sharp lenses would always make me long for the Sigma 40mm Art. Its not for everyone, but its a great lens and I love it.

Read the reviews here and elsewhere ….sounded great but was Leary….BH had a great sale, so purchased….Not disappointed…….fantastic lens As everyone else has said….super sharp….fantastic contrast…..really, great lens….40mm is nice perspective compared to niftyfifty……….just know…as everyone has said……lens is BIG….lens is HUGE….lens is HEAVY…..but as a photographic tool….is amazing…..

Love the 40mm focal length and this newish Sigma ART prime ticks all the boxes. Clean, crisp, sharp, neutral. Looking forward to pairing this with the new C500 Mkii.

just an awesome lens. I have a few other lenses but I have not used Tham since I got the Sigma 40mm f1.4 DG HSM Art.

Really heavy, like a brick. If Sony comes out with a 40mm 1.4 GM lens, I would no doubt get that instead.It will do for now though.

Like the title this Sigma 40mm Art is a phenomenal lens. So if its phenomenal why a 4star right I took off a star for focus shift and lack of Microcontrast.The focus shift isnt as bad as the 50mil Art I had and the field curvature of the 40 is flat as I can tell .The microcontrast or innertonal detail is lacking. Youll notice this most in portraits and high contrast situations or in pictures of flowers . Or thats where Im noticing it . In good lighting its not so noticeable.The good is its the best focusing Sigma Art Ive owned . Thats on a DSLR which is so much more demanding upon lens performance than a mirrorless because of the mirrors in the dslr. Edge to edge top to bottom it hits focus. Most of the older Sigma arts you had to use the center or central focal points well not this lens . And its sharp edge to edge , corner to corner .The colors are great and seemingly accurate. Not as greenishwarming as some older Sigmas . For architectural its so nice . The image is just so perfect in most every way and the great colors buildings look the way they should and maybe better than real life . Havent shot much landscape with it yet but plan to a lot . What I have looks promising for sure .I shoot live music photography and videography and this lens excels at this . Low light , high contrast and backlit . Nails the focus from f1.4 to f2.8 time and time again in these tough situations where Ive struggled with a much more expensive lens. But the more expensive Nikon 70200 f2.8 e fl vr has more innertonal detail. It hunts and misses focus in the tough lighting situations that this lens rocks it .Wrapping this up , its a great lens Oh one more thing , Ive shot several documentary events with this lens . Dang This is perfect , low light, no annoying flash and nailing focus . The 40mm focal lenght is so so useful indoors and out .

Its a 40mm which means two steps back its a 35mm, two steps forward it becomes a 50mm. Very sharp. 40mm is a very goo for my landscape photography. Well built and big.

First off i LOVE this lens I was debating between getting this or the Sony G MASTER 135mm 1.8. I wanted a FAST lens, a PORTRAIT lens, a lens I could use for ASTROPHOTOGRAPHY, and a lens for LANDSCAPE photography. BONUS BOKEA Needless to say I am happy with my decision. The following photo was taken of my Yorkie NATALIE Camera Settings ISO 2000, 0EV, 1.4, 1160th sec. on a Sony A6500.Handheld.

I had spent several weeks reading about this lens before I decided to purchase it. Im a landscape photographer and 90 of my photographs are interior forest captures, primarily of waterfalls in the Appalachian mountains. I use the Sony A7 RII and A7 RIII cameras. I already own the 1635 f2.8 GM and the 2470 f2.8 GM which both are great zoom lenses. As far as primes, I use the 35mm 1.4 Sony Zeiss, the 50mm 1.4 Sony Zeiss and the 55mm 1.8 Sony Zeiss.. What I felt I needed was a great prime lens that performed at least at the level or beyond the level particularly of the 50mm 1.4. Because I make many of my photographs just after sunrise or when the sun is low in the horizon, natural light is low, and in many of the locations there are dense tree canopies shading the area. Based on my experience, the 1.4 aperture suits these conditions more favorably. While I really appreciate the ther two GM zoom lenses I use, I prefer using the faster primes based on the lighting and image quality. In several instances, I have found myself in an uncompromising location while composing a capture due to the physical constraints of my location…the 35mm was a bit too wide with the subject too distant…the 50mm brought me too close to the subject. I felt I needed a lens with an inbetween focal length that would perform at least on a comparable level or better. I made the decision to buy the Sigma 40mm 1.4 Art lens and am so pleased to confirm this lens is a complete winner. This lens, along with only a very few others, rates as one of the most sharp, if not the most sharp and well made lens built to date. There are no compromises in the design and build quality of this lens. It is clearly obvious that Sigma knew what they wanted to accomplish and they set out to accomplish it to the very best of their ability. This lens is a first rate performer in a unique class of distinction. Aside from sharpness, the color rendering of this lens is beautifully and richly natural to the eye. Everything about this lens is first rate. Aside from the lens, the strapped carrying case is a nice addition although Ill probably never use it. As far as lens hoods are concerned, the lens hoods of all the other camera manufacturers pale in comparison to the locking lens hood Sigma designed for this lens. I found it so refreshing for a change to find, appreciate and respect the uncompromised integrity of Sigmas 40mm 1.4 Art especially in an age where other manufacturers constantly scramble and compromise the design of their products to gratify the notions and wants of the conformist fickle masses. Thank you Sigma for your design and release of this winner of a great lens.

Got this wonderful lens at a five hundred dollar discount, and am very happy I pulled the trigger. If I were on the Sony platform, probably would have opted for the Sigma 35mm f1.2, but since Im on Canon, this optic was my closest choice.Extremely high acutance and micro contrast from corner to corner, even wide open, becoming perfect when stopped down to f4 and f5.6. See 100 percent crop from full frame image, both attached to my review, both minimally sharpened setting 2 in Canon Digital Photo Professional.Focuses quickly and accurately on my Canon R5, but exhibits poor, inaccurate focus from wide open to f4 on my 5D IV.Longitudinal chromatic aberrations are well controlled compared to the Sigma 35mm f1.2, bokeh and focus falloff are very good but not quite as nice, while focus speed is pretty good but again not quite up to the 35mm f1.2 level.All in all, a spectacular optic, suitably for environmental portraits, focus stacking, panorama stitching, and general use. Heavy and large, but totally worth it.

Dies ist wohl eins der schrfsten Objektive, das Sigma gebaut hat. Es ist nicht ganz leicht aber in der Klasse um 1000, gibt es kaum was vergleichbares. An der A7 III nutze ich es meist fr Portraitshootings.

First off i LOVE this lens I was debating between getting this or the Sony G MASTER 135mm 1.8. I wanted a FAST lens, a PORTRAIT lens, a lens I could use for ASTROPHOTOGRAPHY, and a lens for LANDSCAPE photography. BONUS BOKEA Needless to say I am happy with my decision. The following photo was taken of my Yorkie NATALIE Camera Settings ISO 2000, 0EV, 1.4, 1160th sec. on a Sony A6500.Handheld.

This 40mm Art is not like other art lenses which are already great. in sharpness is outperforms its 85mm 1.4 art brother. also outperforms zeiss batis and zeiss otus…In fact it is a Cine grade lens in consumer category. Been comparing it with 70200 IS2 and 85mm art i can say that it is a hidden gemif you are oversmart you can check my findings from the findings of digital picturehttpswww.thedigitalpicture.comReviewsISO12233SampleCrops.aspxLens1392Camera979Sample0FLI0API4LensComp1072CameraComp979SampleComp0FLIComp1APIComp0

Most buitofully rendering glass in that price range. Definitely sharpest lens I ever owed. Its size is 100 justified bt the performance.

This is the first time Ive gone for a Sigma lens, previously sticking with Nikon and Zeiss glass. Simply put, Im floored by the build quality of this lens and the images that Ive gotten with it so far are incredible. I wanted a fast lens in the 35mm range as I often shoot night grape harvests in the Napa Valley. This will be a perfect addition to my kit as it balances perfectly with my D850, focuses accurately and FAST It will definitely be in the vineyards with me next harvest. In the meantime, it will get some landscape work and we will see how it stacks up against the Zeiss Milvus 1.4 25 mm. I think it will do just fine.
Luis –
No 40mm can touch the performance of this lens…simple as that. Check the lensrenal tests for example. The resolution numbers from center to edge are stunning. This is as good as it gets.Yet it is big but with this performance, you cannot argue with it.
Russ –
I am in love with this lens. Colors are vivid out of camera and very little postprocessing is required to make them look great for my general hobby and family photos. I am using this lens on a Sony A7RII and A7RIV. It keeps up well with both cameras and can be extremely fun to pixelpeep with.I have noticed the lens lags a bit behind my Sony branded glass when it comes to autofocus I get less shots that are perfectly in focus overall. However, the colors and COMPLETE LACK OF ANY CHROMATIC ABBERATION, make this lens an 1010 for me. Cant wait to spend more time learning how to maximize this lenss potential

I am blown away at the sharpness of this lens. Its heavy, but will remain in my camera bag for the time being. Astounding.

Like the title this Sigma 40mm Art is a phenomenal lens. So if its phenomenal why a 4star right I took off a star for focus shift and lack of Microcontrast.The focus shift isnt as bad as the 50mil Art I had and the field curvature of the 40 is flat as I can tell .The microcontrast or innertonal detail is lacking. Youll notice this most in portraits and high contrast situations or in pictures of flowers . Or thats where Im noticing it . In good lighting its not so noticeable.The good is its the best focusing Sigma Art Ive owned . Thats on a DSLR which is so much more demanding upon lens performance than a mirrorless because of the mirrors in the dslr. Edge to edge top to bottom it hits focus. Most of the older Sigma arts you had to use the center or central focal points well not this lens . And its sharp edge to edge , corner to corner .The colors are great and seemingly accurate. Not as greenishwarming as some older Sigmas . For architectural its so nice . The image is just so perfect in most every way and the great colors buildings look the way they should and maybe better than real life . Havent shot much landscape with it yet but plan to a lot . What I have looks promising for sure .I shoot live music photography and videography and this lens excels at this . Low light , high contrast and backlit . Nails the focus from f1.4 to f2.8 time and time again in these tough situations where Ive struggled with a much more expensive lens. But the more expensive Nikon 70200 f2.8 e fl vr has more innertonal detail. It hunts and misses focus in the tough lighting situations that this lens rocks it .Wrapping this up , its a great lens Oh one more thing , Ive shot several documentary events with this lens . Dang This is perfect , low light, no annoying flash and nailing focus . The 40mm focal lenght is so so useful indoors and out .

I use this on my Sony A7iii with the MC11 adapter. The lens is too big and heavy, but I knew that going in.Once you accept the sizeweight, this is an incredible lens. I love this focal length to cover indoor events. Focus is resoanably fast but accurate. Images are sharp and contrasy. The last few events I have used OOC jpgs even though I also shot in RAW the images were that good in jpg.I mostly shoot wide open indoors and the subject separation is very good.Overall, a fantastic lens. Highly recommended.

I own most of the Sigma Art prime lenses. When I buy a new lens, I test it for sharpness using a test chart. The Nikon D850 camera body is theoretically capable of resolving about 115 lines per mm lpm. Having already owned the Sigma 35mm and 55mm Art lenses, I questioned my need for a 40mm lens. But after seeing Sigmas published MTF curves, which appear better than those of the other 2 lenses, I bought the 40mm lens, and Im glad I did. My lens resolution target goes from 100 lpm to 120 lpm. so 100 lpm is my limit for the D850. At f1.4, my Sigma 40mm Art lens resolved 90 lpm center, 90 edge, and 80 corner. At f2.8, it resolved 100 lpm center, 100 edge, and 90 corner, an amazing result. Because the depth of field at these wide apertures is so shallow, I found critical focus with the D850 is best done by manually focusing in Live View with an external magnifier in order to obtain the peak maximum of resolution. This applies to even after adjusting the AFFT with the Sigma dock. Chromatic abberation and distortion are also extremely wellcontrolled with this lens. My only negative is that, for a 40mm lens, it is big and heavy. It would be nice if Sigma would come out with Art quality lenses at smaller apertures to reduce their size and weight. I have found this 40mm lens to be comparable in sharpness to the 55mm Zeiss Otis lens, but the Otis lens is manual focus and I will be able to use this Sigma lens for focus stacking with the D850.
John –
Really heavy, like a brick. If Sony comes out with a 40mm 1.4 GM lens, I would no doubt get that instead.It will do for now though.
kevin –
Having a D850 and a few other Sigma lenses I wanted something a bit different. Lets be honest, for the most part 40mm isnt a go to lens for most. Having seen other reviews and watched a ton of YouTube videos I went for it. Absolutely worth it, the sharpness and detail this lens has is incredible. While it is a little heavier, its worth the extra weight in your camera bag for the results. Wide open it delivers stunning images, at f4 the results are stellar. It will be a mainstay in my backpack, while it is a bit expensive and the 40mm may seem a little obscure once you see the results it will become one of your favorite lenses.

I had spent several weeks reading about this lens before I decided to purchase it. Im a landscape photographer and 90 of my photographs are interior forest captures, primarily of waterfalls in the Appalachian mountains. I use the Sony A7 RII and A7 RIII cameras. I already own the 1635 f2.8 GM and the 2470 f2.8 GM which both are great zoom lenses. As far as primes, I use the 35mm 1.4 Sony Zeiss, the 50mm 1.4 Sony Zeiss and the 55mm 1.8 Sony Zeiss.. What I felt I needed was a great prime lens that performed at least at the level or beyond the level particularly of the 50mm 1.4. Because I make many of my photographs just after sunrise or when the sun is low in the horizon, natural light is low, and in many of the locations there are dense tree canopies shading the area. Based on my experience, the 1.4 aperture suits these conditions more favorably. While I really appreciate the ther two GM zoom lenses I use, I prefer using the faster primes based on the lighting and image quality. In several instances, I have found myself in an uncompromising location while composing a capture due to the physical constraints of my location…the 35mm was a bit too wide with the subject too distant…the 50mm brought me too close to the subject. I felt I needed a lens with an inbetween focal length that would perform at least on a comparable level or better. I made the decision to buy the Sigma 40mm 1.4 Art lens and am so pleased to confirm this lens is a complete winner. This lens, along with only a very few others, rates as one of the most sharp, if not the most sharp and well made lens built to date. There are no compromises in the design and build quality of this lens. It is clearly obvious that Sigma knew what they wanted to accomplish and they set out to accomplish it to the very best of their ability.

Phenomenal sharpness and great colors across the frame. Autofocus is fast enough, and bokeh is beautiful. Heavy for the focal length, but the results are worth it. 40mm can work like both 35mm and 50mm, a really convenient length for general use.

I have wanted to get this lens for 2 years. I finally could afford it when BH offered a lower price for one day in the DealZone. I do landscape photography and family photos with a Nikon D850 and a Nikon Z6. It is everything I had hoped and expected it to be very sharp on the focus plane across the frame with a smooth transition to the out of focus areas. One caution if you use this on a DSLR and plan to use it wide open then get the Sigma USB Dock and perform the autofocus fine tuning to ensure accurate focus. After that the focus has been very consistent on my D850.

I own several Sigma Art, Sport and Contemporary lenses, so it wasnt a great leap for me to buy the Sigma 40mm f1.4 DG HSM Art Lens. Yes, its heavier than the Nikon AFS Nikkor 35mm f1.8 G ED lens that I used as a partial trade for this lens. But, I REALLY like a sharp lens, and while the Nikon was a nice lens, I wanted something better. And, even though Im 73 years old, I dont mind the heft of my Sigma lenses. I think too much is made out of lugging around an extra pound or so. Although, I did buy the Cotton Carrier CCS G3 Harness1, which I also love. The hardest decision for me was did I go for the Sigma 35mm f1.4 Art the Sigma 50mm 1.4 Art or the 40mm I already have the Sigma 1424mm 1.4 Art, the Sigma 24105mm f4 Art, the Sigma 50100mm f1.8 Art, the Sigma 85mm f1.4 Art, the Sigma 70200mm f2.8 Sport and the Sigma 100400mm f56.3 Contemporary, so my thinking was a combination of thinking that the 40mm would fill a hole that I wanted to fill, AND I knew that my fetish with sharp lenses would always make me long for the Sigma 40mm Art. Its not for everyone, but its a great lens and I love it.

Very sharp corner to corner, no distortion and very contrasty.Taking RAW pictures of the sunrise tried to upload it they look like they have already been edited. When I edit them in Lightroom I just lightly touch them.With other lenses I feel that I have to do a lot more editing to make them look good, with this lens if I do a lot of editing it makes the picture look over edited.I pretty much skip the lens correction unless I want to get rid of the vignette, which often times I keep it in the picture.I love the Sigma Art series lenses, I have 3 of them 50mm, 20mm and I plan on buying the 14 or 16, 105 and maybe the 135 and 85.

This is both the sharpest and heaviest pound for pound lens Ive ever used. I dont want to shoot with anything else. Odd focal length but starting to love it, especially when I know Im getting the best results from it. It is ungodly big and heavy though.

Yes it is a heavy lens. Should it be not heavy For lightness I use other cameras. Build quality is very good.I use it on Nikon D810. Very sharp and fast autofocus. Manual focus is precise and comfortable. You will not regret it.I love it. Highly recommended.

This lens is truly stunning and is one of the sharpest lenses you can ever put on your DSLR. I own the sigma 35 1.4 art since it came out along with the Tamron SP 35 1.8 VC. Both come nowhere near the wide open performance of this sigma 40 1.4. If I want the wide open infinity or even close focus performance of the sigma 40mm on the Tamron or sigma 35 I would have to use F5.6 to get what the sigma 40 does at 1.4. Just leaves your jaws wide open with what optical performance is achieved by Sigma.Autofocus is VERY silent, really fast and accurate on my D810. The sigma 40mm did not need any adjustments with the sigma usb dock that I needed to do for my 35mm so that is really great.Chromatic aberrations are virtually nonexistent. My wide open shot in sample displays this. Look at the leaves and lines along the building during a bright sunny day. Amazing performance Coma performance is great as well from what Ive read about even though I rarely shoot the night sky. As far as flaresghosting I have not tested it but according to lens tip review website this was one category it did not score very well due to having so many glass elements. There is also the slight issue of spherical aberration but honestly in my times of testing it and shooting at F1.4 to mainly F8 I did not experience any issues that would be a deal breaker. No lens will ever be perfect. Every optical designer needs to choose what to correct forSigma really cooked up something spectacular here. You will NOT be disappointed. I got this lens when it was on sale for one day at 999 so it was a really great deal at that time. I have attached a few sample images taken with the sigma 40. These images have mainly only the lens profile attached in light room and all are shot at F1.4.

Summary A beast of a lens, with image quality to match. You get what you pay for literally.The goodImage quality is fantastic. Some of Sigmas Art lenses are amazing, some are normal, and some dont seem to cut it, even though the all get the mark. This one is one of the best.Natural looking blur past f2. At the minimum f1.4, the blur starts looking exaggerated like most lenses at that aperture, but some people like that. Past f4, blur is only on the edges and details in the autofocus zone are crystal clear.Quick AF Sigmas agreement with Sony on the Emount specs is paying off. However, if you like or want to manual focus, the focus ring is large and easy for your fingers to find.In addition to the solid Sigma Global Vision construction, actually feels weather sealed. There doesnt seem to be any openings to the environment.The badHeavy. This is not a mirrorless lens. This is a beast lens not for the faint of heart. You know just by picking it up that there is serious glass in there. It doesnt balance well if you like holding the camera by the body.Long. This was used on a A7R3. Because of the Emount neck, its longer than for instance a Canon version. However, if you like to handhold the camera by the lens like I do, it fits fine.The other stuffThis 40mm was supposedly built from the cinema version, but there arent any cinematype features at all. For instance, the Sony 135mm GM has an iris ring that can be declicked like that on a cinema lens. The Sigma appears no different than any other Art lens in that respect.

I was lucky to snag this lens for 899 on Deal Zone. Though I own a Sony Alpha 7RII, I bought it in the Canon mount as I eventually plan on using it on the Sigma full frame foveon sensor camera the L mount version of this lens wasnt on sale.This is by far the sharpest lens Ive used considering the entire frame but at the very centre of the frame, I feel the Sigma 70mm f2.8 macro beats this one. The 70mm macro clearly feels sharper at the centre but overall this is a stunning lens and anyone who is on the fence of shouldshould not buy should go ahead and buy it even at its retail price of 1399. Well worth the money.Stunning image quality, stunning build quality, not heavy if held by the lens or 2 handed, 4 year warranty and Made in Japan.Waiting to pair this lens and the 70mm f2.8 macro with the full frame foveon sensor sharpest lenses on the best sensor technology.
Hilmi –
But who cares.Sharp from edge to edge. I own also a zeiss 50 mm 1.4. I love it so much but this is better. From art perspective and from light transparency. Autofocus is very very quick and nearly no miss in five days experience with my d810. I am sure all of you are waiting for dxo results etc to decide between tokina opera or cheaper 50 mm art but Let me remind you this is also for 8K video. It has future.

This was purchased to replace a Canon 50mm f1.4. First thing to notice is a big step up in sharpness, as well as bulk and weight. Autofocus is adequate for cat portraits as long as they are sitting still. There is a chance that autofocus is not deadon at first try, repeatedly half pressing shutter button appeared to zeroin on the focus point.When using 5D4 incamera HDR mode, during the second of the three consecutive exposures, I received an error code stating camera failed to communicate with the lens. I have to dismount the lens to clear the error. This phenomenon is repeatable using this lens. However, my 1424 f2.8 works fine in HDR mode.As a third party lens, this Sigma has the optical feature I want at a very reasonable price and limitations that I can live with. Good job Sigma

William –
I must admit I was impressed by the reviews and opinions I have read about this lens. All I can say is that it might be even better. Wide open at f1.4 it is sharp corner to corner. Backgrounds are outstanding for a 40mm lens. It is truly a multiuse top notch lens for both wide apertures and landscape apertures. The weight could be a problem for some, but very manageable I would think for most. On my DSLRs it needed a general same sigma dock adjustment at all distances. With the adjustment all results were stellar with minor in camera adjustments on my D850 and no adjustment on my D810 and D5. Results are also stellar on my Z6 with the FTZ adapter, and as good as the Z 50mm 1.8 lens is, the sigma has much better backgrounds with comparable or better sharpness, and of course more weight. Stellar image quality still comes at a price. Overall highly recommended
DAVID –
The good1 Sharp, like my camera suddenly got 5 more mega pixels.2 just as accurate focus as native glass, far better than the other half dozen sigma art lenses I own.3 auto focus is fast enough for portrait work4 weather sealing5 on my apsc cameras this is a 65mm lens, which is a great angle of view for portraits.The bad1 its heavy2 no ISOS, which is like almost every other prime. Canon, wheres the IBIS
Jack –
The sharpest lens I have ever had. I have the very demanding Canon R5 and own several native RF lenses and some older EF L. This lens is by far the best of all, the sharpest images I have ever seen.The drawback, it is huge and heavy, and I am getting old. However, it has become my favorite lens. Just incredible quality. I have some other Sigma Art EF lenses and one EFM 30mm. This is just another league.

I had heard good things about the Sigma 40mm, with the only negative being that the lens is large and heavy. This lens is a statement lens, and statement lenses typically have a clear goal in mind to be among the best in image quality and resolution. In that regard this lens does not disappoint, as the sharpness is phenomenal from cornertocorner. If you want a statement lens, and can accept the cons that come with statement lenses, then this lens is for you. If you love to pixelpeep, and crave high resolution, then you should consider this lens.

I have the 35 and the 50 art, and friends have let me borrow other art lenses. This lens is better than all of them. It is Zeiss like in quality, and it is unlikely you will find a sharper lens. In addition, bokeh seems to be very nice, and the lens has a pop often associated with Zeiss lenses. The downside of course is the size and weight. It is big, it is heavy, but there is really nothing better, and so you have a choice to make. If you want the best, you will have to deal with the size and weight. The odd focal length is fine for me, yet I understand 40mm might be strange for others.

I wanted a fast lens in the 35mm range as I often shoot night grape harvests in the Napa Valley. This will be a perfect addition to my kit as it balances perfectly with my D850, focuses accurately and FAST It will definitely be in the vineyards with me next harvest. In the meantime, it will get some landscape work and we will see how it stacks up against the Zeiss Milvus 1.4 25 mm. I think it will do just fine.

Its a 40mm which means two steps back its a 35mm, two steps forward it becomes a 50mm. Very sharp. 40mm is a very goo for my landscape photography. Well built and big.

The sharpest lens I have ever had. I have the very demanding Canon R5 and own several native RF lenses and some older EF L. This lens is by far the best of all, the sharpest images I have ever seen.The drawback, it is huge and heavy, and I am getting old. However, it has become my favorite lens. Just incredible quality. I have some other Sigma Art EF lenses and one EFM 30mm. This is just another league.

First of all, everyones review has stated how great this lens is. I will submit the following photo I took near my home 3 miles away and provide photo data. May 30th, 2021 SIGMA 40mm DGDN ART 1.4 f1.4 ISO 100 EV 0 25 second exposure 954 P.M. on Sony A7RIII on a carbon fiber tripod.

Its a real challenge to take full advantage of its optical excellence. For maximum acuity on either my Z7 or my D850 I had to mount it on a tripod, manually focus on live view, delay the shutter 3 seconds and be sure there was no wind. Doing this gives me technically spectacular results. My copy does have quite noticeable focus shift when changing f stops.A more casual approach using auto focus yields nice result but not spectacular ones.And yes…the thing weighs a ton.

I was lucky to snag this lens for 899 on Deal Zone. Though I own a Sony Alpha 7RII, I bought it in the Canon mount as I eventually plan on using it on the Sigma full frame foveon sensor camera the L mount version of this lens wasnt on sale.This is by far the sharpest lens Ive used considering the entire frame but at the very centre of the frame, I feel the Sigma 70mm f2.8 macro beats this one. The 70mm macro clearly feels sharper at the centre but overall this is a stunning lens and anyone who is on the fence of shouldshould not buy should go ahead and buy it even at its retail price of 1399. Well worth the money.Stunning image quality, stunning build quality, not heavy if held by the lens or 2 handed, 4 year warranty and Made in Japan.Waiting to pair this lens and the 70mm f2.8 macro with the full frame foveon sensor sharpest lenses on the best sensor technology.

This was purchased to replace a Canon 50mm f1.4. First thing to notice is a big step up in sharpness, as well as bulk and weight. Autofocus is adequate for cat portraits as long as they are sitting still. There is a chance that autofocus is not deadon at first try, repeatedly half pressing shutter button appeared to zeroin on the focus point.When using 5D4 incamera HDR mode, during the second of the three consecutive exposures, I received an error code stating camera failed to communicate with the lens. I have to dismount the lens to clear the error. This phenomenon is repeatable using this lens. However, my 1424 f2.8 works fine in HDR mode.As a third party lens, this Sigma has the optical feature I want at a very reasonable price and limitations that I can live with. Good job Sigma
