Cosina officially announces the Voigtlander NOKTON RF 75mm f/1.5



The new lens will be available in April for ¥135,000 ($900 USD).




The NOKTON 75mm F1 .5 Aspherical RF mount is a large-aperture medium-telephoto lens for full-frame mirrorless cameras with Canon RF mount. Despite its large aperture with a maximum aperture of F1.5, it is both compact and high-performance. By adopting an aspherical lens, excellent descriptive power is demonstrated from the wide aperture.




Implemented with an optical system optimized for the image sensor of a mirrorless camera that uses a Canon RF mount. This lens has a full-frame image circle and can be used with both full-frame and APS-C mirrorless cameras.



The lens mount is equipped with electronic contacts to enable telecommunication between the lens and the body. In combination with the body of the Canon EOS R system, it supports Exif information, in-body image stabilization (3-axis), and three types of focus assist functions (magnification, peaking, and focus guide).



The all-metal helicoid unit, which is machined and adjusted with high precision, and the use of high-quality grease that produces moderate torque, achieve smooth focusing with a sense of operation. It allows for subtle focus adjustment.



Although it is a large-aperture lens with a maximum aperture of F1.5, the minimum aperture can be set up to F32. At f/1.5 with the maximum aperture, you can enjoy a large bokeh, while at f/32 at the smallest aperture, you can get deep focus.



In order to make the holes formed by the diaphragm blades closer to a circular shape, a 12-element diaphragm is adopted. The out-of-focus part is a natural depiction, and the point light source is not a polygon, but a round and soft bokeh.



The aperture ring has a click switching mechanism, and it is possible to open and close the aperture steplessly without being affected by clicks when recording videos or adjusting the fine depth of focus
