Adapter for Nikon F-Lenses to Contax/Kiev RF or Nikon RF

[hofmannra]

Hello,

I'm new here and have a question. I have some Nikon SLR bodies with manual Nikon F-mount lenses. Now I got a Kiev 4 which is a copy of a former Contax rangefinder. Are there any adapters to mount Nikon F-lenses to Contax/Kiev RF? The mount is identical with the Nikon S-mount (RF), but there is an incompatibility with focussing but this is no problem with wide angle lenses. Thank You.

Welcome!

Problem is not really mount, problem is huge film register difference. Even if you can mount it working distance from subject will be not more than 30-40cm or less. Nikon worst body from all SLR to mount other lenses than Nikon. If you would like to try many lenses , buy a more compatible body.

Canon, 4/3 , micro 4/3 , Sony Nex etc. Mirror less bodies are most compatible ones.

Attila I think you misunderstood. Rainer is asking if there are adapters to mount Nikkor lenses on Kiev body.
Rainer, I don't know, but like always google and Ebay search are your friends. Punt in search field " Nikkor Kiev" and see what comes up. I foresee a big problem however, the lenses will not be rangefinder coupled, so you will have to focus using a separate viewfinder or guesstimate, and the scale on the lens (which may or may not prove faithful depending on the adapter).

Yes, thanks I didn't understood well. I never seen such a similar adapter.

RF guys rare or never want to use SLR lens on their RF body.

It would be possible by register distance - but rangefinder focusing would only be possible for lenses with around 52mm focal length, as that is what the internal helicoid is designed for. As the real focal length of SLR lenses is mostly unknown and normals are about the only lens there is no lack of in the Contax/Kiev/Nikon RF universe, nobody ever has bothered to make such an adapter.

Corresponding adapters seem to exist for Leica M mount, where they are a bit more justified given the existence of three digital M mount bodies, but even these are rare niche products I've never personally seen.

The Nikon RF mount is entirely different from Nikon F - these two are not mutually exchangeable, and never were. Nikon RF is almost the same as Contax, but it has a different angular progression, and a different base focal length. Wides are interchangeable between Nikon RF and Contax, but normals and long lenses have considerable front/back focus at the near end.

Thank you for your answers. I found out, that there are two Voigtlander ultra wide lenses 12/5.6 and 15/4.5 for Nikon F, useable with mirror-lock-up. For this lenses Voigtlander sold an adapter (FS-adapter) for use at Nikon rangefinder. This adapter should fit for Other Nikkor lenses too. But its very hard to find and very expensive.
There was a discussion at rangefinder.com http://www.rangefinderforum.com/forums/showthread.php?t=42351

I think it would be easier to look for directly fitting jupiter lenses
