Japanese manufacturer Cosina, makers of the Voigtlander lenses has officially teased their first RF mount lens. The new lens is teased with “electrical” contacts which would help with EXIF data, but do not expect an autofocus lens.

I would expect a well made prime lens from Cosina for the RF mount. It will be well built, and optically excellent for an affordable price.

We'll see the announcement this week.

I wonder if they will release one of their APO Lanthars optimised for RF. The 35mm f2 is excellent but in particular the 50mm f2 is even better and one of very the best lenses ever made.

Saw a comparison between the M mount version against the Leica equivalent and the Voigtländer matched it optically despite being $8000 cheaper.

If it's the 35 or 50mm APO lens I'll preorder it the second I'm able to. The APO Lanthars are the only third party lenses I'm jealous of other systems for having.

A manual focus lens with electrical contacts might be useful if it can utilize the manual focusing guides function found in R cameras. Although I do not know if this is possible. Might not be.

My Zeiss EF lens allows for the manual focusing guide when I adapt it so I would guess the Voigtlander would as well.

They had cut back their EF lenses long time back so this would be a welcome move from Cosina.

Thank you for the feedback. Honestly, I likely will pass on the lens since I already own the Canon RF 28-70 mm f2 which is much more flexible. Moreover, if the rumored retail price of $1800 is correct that is very close to the Canon 50 mm f1.2 which adds AF.
