Carl Zeiss Jena Biotar 1.4/50mm on Canon or Nikon?

[haring]

Is it possible to mount a Carl Zeiss Jena Biotar 1.4/50mm lens on a Canon or Nikon DSLR? If yes, which adapter do you recommend?
Thanks!

Erm, which Zeiss Jena Biotar do you mean?
Speaking of Biotars, there is only the 2/58 and the 1.5/75, the 1.4/50 is a Prakticar in B Mount which is a mirrored Pentax K mount.
Adapting PB is difficult.

Interesting. I didn't know there was a 1.4/50mm Biotar. The legendary 2.0/58mm Biotar was quite popular on the old Exakta cameras.

Yep, I have one on my Exakta VX and it is great.
I have the „red T“ variation with a fine Zeiss coating.

Wait, there is one for the Pentaka 16 which is a 16mm cinematic camera. That one is a 1.4/50 but I doubt the image circle is large enough for 35mm.
If you want to adapt to Canon I suggest getting lenses in Exa mount. They are plentiful, relatively cheap and of good quality.
Exaktas were the standard for quite a while, M42 only became popular when all the digital people discovered how good the old optics are. Cheap as well, at least compared to the optics intended for the systems.

I see! So Sony is the winner. It wouldn't mount on a Canon or Nikon. Sony a7s or any full frame Sony "E" mount I guess.
What kind of adapter do I need for the Sony full frame cameras?
I need a lens which has a M42 mount for Sont E mount, I guess, right?

Since the distance for E mount is smaller than that of all the reflex lenses it doesn't really matter if it is M42 or Nikon or what, it would be good to know the lens mount of your Biotar.
