The Voigtlander Nokton 40mm f/1.2 Aspherical for Canon RF is an ultra-fast standard prime with electronic communication for Canon's RF mirrorless system. At f/1.2 and 40mm, it provides extraordinary shallow DOF at the natural standard perspective. The Nokton designation and aspherical element indicate premium optics. Electronic coupling provides EXIF and aperture control.
Optical performance is very good. Sharpness is good from f/1.2, becoming excellent by f/2. The aspherical element controls aberrations well for the extreme specification. The 40mm is increasingly favoured as a more natural perspective than 50mm. Bokeh is smooth and three-dimensional. The electronic communication makes this significantly more practical on RF bodies.
