I am wondering what lens this is- Non- leica collapsible 50mm? Or?

Jupiter-8. Made in 1956 in the former Soviet Union.  They can be decent lenses.... from around that time (1956).

Right, a Jupiter 8 - based on Zeiss Jena Sonnar 50 f2 for Contax : see for comparision one for sale here :

rfaspen and Luigi have correctly indicated the type of this lens. It is not collapsible.

It may also not be fully compatible with LTM Leica bodies as the FSU FED and Zori cameras used a slightly different lens-flange to film-plane distance.

Thanks everyone- how about this lens:

I don't think that the FED or Zorki differed in the flange-to-film distance. They were "real" Leica copies. The problem is that the Jupiter lenses were originally made for the Kiev-Cameras. They - being Zeiss-Ikon Contax copies - differed considerably. When these lenses for the Kiev were adapted to M39 mount, it is not guaranteed that the different flange to film distance was corrected as well. So one should test them or perhaps better look for the original Kiev-mount items and use an adapter (if one finds one.... ).

The other lens shown in #6 is difficult to identify because of the a strange cap. It looks like an early version of the Jupiter 9 - which was a copy of the Zeiss Sonnar 2/85mm. This is usually a rather good lens though it has the same - or because of the small depth of focus even more - problems with flange-to-film distance as other Jupiter lenses even though a lot have been produced with M 39-mount. I have a later copy in black which will never focus exactly. Only LiveView might help. Since you cannot see the lenses mount on the photo, it might even be an "original" Jupiter 9 for the Kiev/Contax-mount.

It's been a while since I did my research into this matter, Uli, so I might be remembering things wrong.

I have a few dozen FSU lenses and the only ones which I have tried that worked with my Leica were the short lenses; anything 50mm and above was out. One reason might be, as you state, that the Jupiters were all built to Zeiss designs. I do have some pre-WWII FED lenses (as well as some produced during the conflict) which, AFAIK, were modelled on the Leitz lenses so these might well work correctly.

I have also read a suggestion that the lens cam slope (and, therefore, cam-follower profile) of Zorki cameras don't have exactly the same shape nor degree of movement (I remember the figure 0.020" was mentioned) in comparison to the Leica bodies but have not the tools to hand needed to either confirm or deny this claim.

I'll have to try out the pre-1945 lenses (all 50mm f3.5 'Elmar' style) when I get a moment to see whether these fare better than the later ones.

I bought a 50mm f1.5 Jupiter 3 but that did not focus correctly, quite a long way out and I do read that they have to be adjusted for Leica use. But the Jupiter 8 lenses seem ok. And an 85mm Jupiter I had focussed ok. I sold that when I got a Zeiss Sonnar version, claiming to be original Zeiss but possibly postwar Russian build.

i have a nice prewar FED 1. It seems that prewar FEDs did not have the standardised Leica flange, rather like the Leica non-standard period the lenses were matched to the camera bodies. This one has a shorter flange distance which matches a non-standard Elmar I have, close enough to use.

To stay in Soviet... could be the Jupiter 9 85mm f2 (another "Sonnar clone")... extended at short focus distance....  no other pictures ? Jupiter 9 focused to 1,15m... not 1,25 but who knows about variants... 🤔

(the subsequent FL for Soviet was the FED 100 f6,3... but is different in shape and size)

If it is not Russian... I give up... there are so many... the writing "AM..." suggests nothing to me... 🤒... but a fine presentation case anyway 🙂

No other pictures sadly. I thought maybe it could be a canon lens- as they sometimes used bright stainless steel (chrome?) finishes like that. But it really is hard to tell from that angle. The writing says AMITY SOLAR. I tried googling it with no luck- and don't know if the case is original to the lens anyway.

 

I like the look of that Jupiter 8 lens- now I want to get one to try it out... GAS.

 

thanks for the all the replies.

There were "Sun" Sola" and perhaps "Solar" (all same mfgr) branded LTM lenses.  They were Japanese and they had a variety of focal lengths with more than one 73mm offering.  Maybe one of those?  They came in chrome versions that were rather bright like this one, but the shape and focus ring don't look like any I've seen.

Whatever it is, it appears to be 85-90mm focal length and I think I see a thread mount in that clear cap.  There were so many small brands of LTM...
