ZK Zorki And other uncommon Jupiter lenses

Hello Everyone !


Jacques, Did you try your lens? Does it perform well?

I think I have something pretty similar with a kind of multicoating. Perhaps they made a whole series of multicoated jupiter during the 50's?!






I bought it mostly because of the serial number :).

Cyril.

Hi Cyril!

No, I have not yet tried my "green" Jup 3: too much material, and I have no numerics to try the lenses. Perhaps it will be my next purchase.

As for your Jup 11, I Wonder if you don't have an ungluing of a glass Inside. The irisation on the last photo remembers me one of my postwar Sonnars. Hope I am wrong and it is only the reflexion of the trees!

Amitiйs. Jacques.

Jacques,

Yes,unfortunately one of the glass is a bit unglued in the corner. Do you think it was made using post war Zeiss lens ? It would be really strange. Maybe it was an experimental part ?
To make such a fake would be a nonsense as it was not so expensive ... (Twice the price of a jupititer 11 in average condition).

Amitiйs, Cyril

Hi Cyril,

It's rather the Zeiss Oberkochen lenses (Western production) which are known to have problems of separation. I own one of these lenses s/n 1979274, a 1,5/5cm LTM Sonnar, which has a strong separation inside: a question of glue.

Yours is a Jup, so on the Jena eastern side. These lenses are generally free from this kind of problem. And in 1952, the Jup 11 was surely completely made by KMZ. So, it's certainly an individual problem.

Amitiйs. Jacques.

Hello Jacques,

So it might mean that somewhere around 1952 KMZ experimented some multicoated lenses and issued some of them... It's interesting! And maybe a multicoated version of other jupiter also exists :)

Amitié, Cyril.

Hello everyone !

I found another multicoated jupiter. I could uncrew it and I found a sratched number on the lens block. It seems to be "45" and a Russian "Б". I also found a J-12 of the same kind from 1957.I have still no idea about this multicoated serie of jupiter since I haven't found any information about multicoated jupiters, they seem to be mostly unknown :( ...







Cyril

Hi Cyril,

The two "45" on your lens are there obviously for reasons of mounting, at the factory or a repairman's.
As for the Jup 12, if your question is about the date of changing mono towards multi coating, I don't know. I have made a quick research: no real answer.

A question more to solve?

Jacques.

Hi Jacques!

In fact, since there is no documentation about these lenses, there is a lot of question to solve :). The main answer being why did they start making some multi coated lenses in the early 1950's and then stopped (wasn't it a kind of substential progress for color photo?!) and why so few of theses lenses were produced as they seem to be rare enough... Maybe I'm mistaking but they seem to be as hard to find as ZK ones but not as expensive ecause no one is looking for them :).

Amitiés,
Cyril

Hello everone!

I just bought a BK from 1948 year with a really early number but without zeiss serial on the barrel...
Is it possible? It looks genuine, only the coating is maybe alittle too blue comparing to other zk...

Thanks for answers!

Hello Cyril!

At first sight, the body of your BK seems correct, with its two screws. As for the glasses, of course, I cannot tell. A 1948 BK should have a Zeiss number, I think.
Note that I own three early Jup 12. Two have Zeiss numbers, and the bodies are different on the three ones...

Amitiйs.
And all my wishes to everybody for 2016!
Jacques.

Hi Cyril,
your Jup-12 seems to be the late one. My opinion, it is not a genuine BK-lens. The rear cap seems to be not genuine as well, sorry.

P.S. I bought 2009 two BK lenses from one seller from Moscow, both are fakes (unfortunately I have checked them about 1/2 year later).
May be we have the same seller . You can write me on my Email.


Regards, Alexander

Hello everyone!

All jy wishes for 2016! Hope you will a lot of interesting cameras during the it's ing new year !

This is really disappointing. The fake is really well made it nerfs just a Zeiss number... And its not most difficult to fake ...

Best wishes,

Cyril

I have a very uncommon Jupiter-8,a 1954 one found on a Zorki-3. The usual J-8s have 3 screws on the back.

Cheers

Zhang

Hi Jed,

Thanks for the input. I guess I did not pay much attention to these details before. I had a look at all the J-8s on that auction site last night and it seems that this type of J-8s are very common. In fact, all the J-8s made before 1954 including the ZKs are without the 3 screws. J-8s made between 1955 and sometime in 1959 has the focusing lever,and 3 screws , and J-8s made later are without the lever.

Cheers,

Zhang
