What mount is that? - Tessar 50mm 3.5

[vfalendysh]

Hello,

A while ago I got this lens from big auction website..
Seller described it as an Exacta mount lens. It had only front view picture. It was bargain price so I got it.

It is Carl Zeiss Jena Tessar 50mm 3.5 lens with screw mount. It is about 39mm.

Lens itself really looks like Exacta's Tessar, just mount is different.
Search online did not give me any results.



Does somebody know what kind of mount is that?

Thanks

Victor

Enlarger lens? What do you mean "about 39mm"? If its 39mm its probably a m39 or lieca thread mount. Possibly contax rangefinder but I have never seen one to guess on the contax.
Do you have a 39mm rangefinder you can try it on?

I think the thread diameter of your lens really is 40mm. This diameter was used in early versions of the Praktiflex cameras.

Thanks guys! Looks like Jordi is right.
I compared it to my Industar from FED which has Leica mounta and it is little bit bigger. Not exactly 39mm..

Thanks again!

Contax rang finder cameras are bayonet fitting not screw.

Gotcha, I remembered reading about an screw mount that was similar to LSM but wasnt. I wasnt sure what the make was, no I know it wasnt an older contax. THanks
