Description
NOKTON 40mm F1.2 Aspherical is a large diameter manual focus lens specifically for Canon RF mounts. Covers full-size image circles and the optical design is optimized for image sensors on Canon R system cameras. It does not rely on the function of electronic lens optical correction within the camera, but it is designed to show the performance of the lens as an image
This lens is equipped with electronic contacts to achieve telecommunication between the lens and the body. Combined with the body of the Canon EOS R system, it supports Exif information, in-body shake correction (3-axis )*2 as well as three focus assist functions (magnified display, peeking, and focus guide). The lens consists of two of 8 elements in 6 groups with a double-sided aspherical lens. Compact in size, but with a full-size 40mm lens, this lens achieves an incredible large aperture of F1.2. You can enjoy the smooth and large bokeh flavor with peace of mind from opening aperture
The 40mm focal length is equivalent to 60mm for APS-C sized cameras, and it is highly versatile and can be used as a standard lens with full size or APS-C size
The shortest shooting distance of this lens is 0.3m, focusing is only for manual focus. Metal focus ring features a diamond pattern for excellent grip. It is also one of the features of a highly accurate metal helicoid that is stable when installing a focus gear for video on the market and can withstand the constant focus of aperture opening
The aperture is a mechanical control that is directly connected to the operation ring, and it is adjusted on the lens side, not the command dial on the camera side. The aperture ring has a click switching mechanism that allows you to open and close the aperture steplessly without being affected by the click during video shooting or adjusting the fine focus depth. The number of apertures is 10 and is designed to capture the outfocus of the point light in a neat manner. It also comes with a dedicated metal lens hood
