No real importance where the lens comes from: it is absolutely impossible to prove if a ZK without Zeiss numbers is a fake or not.
We know that KMZ received Zeiss parts (and complete lenses too) from Germany.
We suppose they used it regularly: complete lenses first, then spare parts. And of course, these German parts had to be completed by Russian ones.
But we don't know for sure when it occurred, nor for which lenses first, nor for which parts, nor for which mounts.
I think that a 1950 (or perhaps even 1949) LTM 4/13,5cm Zorki can be true without Zeiss number. But a 1950 1,5/5cm Jupiter certainly will be a fake without this Zeiss number. And for the ZK/Jupiter 12, all can be true until 1952, with or without Zeiss number from 1950... As for the ears, sure the Jup 3 and 8 should have them until 1950.
Certainly, all that is very complex. And when we buy such a lens, we must be prepared to think of a possible fake. And of the possibility of re sending it if it does not seem "square".
All that is only what I think, after having examined closely dozens of these lenses. But there is no rule: as I have already said, I own a Jupiter 3, dated of 1974 by KMZ, and with a Zeiss serial number on the back...
Amitiés. Jacques. |

My lens came 5 years ago from sokrat_photo.
He is selling still some nice fakes, but I have not bought any other cameras or lenses by him after this one.

Hi All!!
Mine is coming from Moscowphoto.
I know he sells quite nice fakes or nice cameras. I bought him a Zorki 75 in chrome a few years ago.
Price of lens is result of a negociation. I assume I bought it supposing it could be a fake...

Interesting would be which seller sold these fake lenses. Because for example there is only one seller who offers black Zorki-2C and those are of course not original ones. Then it's save to assume that most lenses from these sellers are fakes. |

Thank you, Jacques.
I have unscrewed my ZK '48 and that is, what I have found inside:

...of course without any Zeiss serial number.

On some series, there is a screw which tights the different parts of the lens, specially on collapsible ones. But not to force if that does not come! I have several lenses with a "cemented" block...

Now, the two parts are side by side:

And here is the Zeiss serial number:

Well, two of my 2/5cm LTM lenses.
Right: a fake 1947 ZK.
Left: a true Sonnar, but non original (baionnet optical part put in a Jupiter 8 body).

The optical block of the Sonnar is half unscrewed (I could have taken the fake ZK: it's just the same):

Hi Alexander!
Perhaps there were in 1948 collapsible and non collapsible LTM lenses. Perhaps, but I doubt. As far as I know, it would be an exception. In 1949, there will be both collapsible and non collapsible lenses.
To be precise, we speak of 2/5cm LTM lenses, not baïonnet ones.
I will make soon some photos about the dismounting of one of my lenses. Tomorrow if I can!
Jacques.

Hello Fred,
that is my lens and I am also not sure if it is genuine. Let's try together.

Jacques, there were both lenses in 1948, "normal" and collapsible.
Could you please show more detailed, how to disassemble the lens to find the number?

There, on the rear part of the lens barrel:
http://www.ussrphoto.com/UserContent/17122014_Jup3-Sonnar.jpg
(it is on a 1,5/5cm, but it's the same on a 2/5cm).
You have to remove the back screw first, then to unscrew the lens barrel by the front part.
It should come, but don't force!
Jacques.

Hi Fred!
I doubt too.
A 1948 ZK should be collapsible, I think. And it should have rings at the diaphragm ring.
But it's only my opinon...
The best should be to dismount it to see if there is a Zeiss number or not. In 1948, they always had it...
Amitiés. Jacques. |
