Voigtlander Nokton 50mm f/1 Aspherical RF mount


At CP+ 2023, Voigtlander was showing the Nokton 50mm f/1 Aspherical, which is their first-ever Canon RF mount lens. It follows in the footsteps of the classic Voigtlander full-frame manual focus lenses.

Despite being a manual lens, it offers support for full electronic communication with an attached Canon RF camera. Because you can transfer EXIF data from the lens to the camera you can see your f-stop and we were also able to have the Canon R5 display manual focus assist.

Given the recent controversy surrounding Canon asking third-party lens manufacturers to stop making AF RF-mount lenses, it would be interesting to see whether or not Cosina had to do a deal with Canon to allow the transfer of EXIF data from the lens to a canon RF camera. I personally think it is more likely that Canon chose to turn a blind eye because this is a manual-only focus lens and thus, it doesn’t directly compete with any of canon’s own lenses.

We had a quick play with the Nokton 50mm f/1 Aspherical at the show and it is a well-built lens that is certainly capable of achieving a very shallow depth of field and nice bokeh when used wide open.


The optical construction of the lens consists of nine elements in seven groups and there is a 12-blade aperture. It is 6.4cm long and it is 7.93cm in diameter. The lens also has a 67mm front filter diameter.
