Strange Large screw mount lens Not M42 -more like 55mm rear

Hello my photo friends....
I recently picked up a nice Schneider Tele-Xenar from a thrift shop and am a bit stumped. I am generally great at identifying lens mounts but this is a bizarre one that I just can not figure out.... Question

This is a Schneider 36cm f5.5 lens in a focusing barrel with a large screw mount design and the lens covers Medium format. It is not m42 but more of a 55mm rear thread size. I generally see this lens fitting Exakta and Leica but never in this focusing mount...

I am calling upon the great Vintage lens mount knowers of FM to decipher what this one is... Very Happy

Thanks all....

I am not one of the great Vintage lens mount knowers here, but it looks like it might be a movie camera or television lens to me. I bet it's really a good lens whatever it's use!

Thanks Jeff,
That has so far been what I have been feeling... I am just not sure which one... It covers medium format so I guess it could even work with 70mm format if desired....


I have been searching aerial cameras, motion picture camera, medium format, etc. I tried to screw a 55mm filter onto it - Very close but not quite... More like a 55.5 to 56mm screw mount rear I guess.

From what I can tell, the lens is from around 1938 (according to its serial number) and it has a matching barrel.

A strange one indeed....

Early Primarflex screw mount ?
That would fit the date.

Bronica S2A 57mm x 1mm thread mount? If so, it has a 101.7mm flange focal distance.

Dont know what the thread was on the early Primarflex mount, but it was big.

Ahhhh luisalegria ... You might have hit the nail on the head with that one.... Primarflex.... I might need to find another Primarflex and test this theory.

Exciting, I think this might be a super rarity for Primarflex if so - generally Zeiss, Boyer, Berthoit and Meyer have the lenses for this mount. I have never seen a Schneider for it... Hmm.

I sold the INOP one that I had a few years back...I am not sure the screw mount size for the camera but this might just be a match. Very Happy

Why me ?
I do not actually own many weird German cameras or weird German lenses.
I wouldn't mind having them though.

Just curious, but is that the aperture diaphragm ring up front, just behind the black arrow? Thanks.

Nice to see my advice to come here and ask has paid off.

Primarflex mount is significantly larger (ø70mm)... Not even Meister Korelle (ø60mm)...


PostPosted: Wed Aug 13, 2014 7:01 am    Post subject: Reply with quote

Guess it is Reflex Korelle which was built with 3 different mounts: bajonet (late), small screw mount around 39-40 (usual) and a big one (for Primoplan and long tele lenses)

Korelle, known to be supplied by Schneider, they did screws as well as this

I believe this is the tread mount associated with Meister-Korelle camera's?

If it was for 6x7 film, it would be a super-wide angle surely?

Well, it is 36cm or 360mm if I have read it correctly - so telephoto definitely.
It would be a lot easier if every manufacturer used the same units of measurement as they do now, but I guess back then there was no agreed standard.
Interesting looking lens
