This lens features a unique switchable aperture ring allowing for clickless operation, ideal for smooth transitions in video. It is equipped with a manual focus ring for precise and consistent focusing, enhanced by a 10-element aperture that creates smooth, circular bokeh.

Build Quality and Features
Voigtlander, a brand synonymous with high-quality lens manufacturing, maintains its reputation with the NOKTON 40mm F1.2 Aspherical lens for Canon RF mount. The lens’s all-metal construction ensures durability and smooth operation. Differing from its Sony E-mount version, this model incorporates contacts for lens communication through the RF mount, enabling it to transmit Exif data and support various focus functions like magnification, peaking, and focus guides.

Versatility in Focal Length and Aperture
The 40mm focal length is ideal for medium shots on full-frame cameras, and with an f/1.2 aperture, it stands out as exceptionally fast for its category. On crop-sensor cameras, the lens offers a 60mm equivalent focal length, allowing for closer framing, particularly useful with high-resolution camera bodies. The lens also includes witness marks on the top for easier operation, though these marks might be less visible when the camera is on a shoulder rig or at eye-level on a tripod.

The Classic Voigtlander Aesthetic
Voigtlander lenses are celebrated for their classic visual appeal. They produce a dreamy effect when wide open, with sharpness becoming more noticeable upon stopping down. This characteristic is reminiscent of traditional lens designs and is a key factor for potential buyers to consider, ensuring that the lens’s aesthetic aligns with their artistic objectives. The 40mm focal length, known for its versatility and distinct look, has become a staple in many photographers’ kits, chosen for its balance between wide and telephoto perspectives.
