ZK and Jupiter

I am looking for ZK lenses (2/50 or 1,5/50) and Jupiter 3 or 8, but only from 1950, in Leica thread mount.
Nothing to trade, so, I buy...

Amitiйs. Jacques.

I'm looking for a Jupiter 3 too, from KMZ only, M39 LTM, B quality would be okay. no matter about the year of production. Also to buy ...

Sorry Jacques that I use your question to pronounce my wish too.

Best regards - Guido

No problem, Guido!
My wish is 1950 only for the Jup' (but they were not produced before) or any year for a ZK.
So, good luck!

Jacques.

Hello Jacques

Thank you for your good wishes. Same to you!

By the way (okay, it's not the best place for such questions): Why ZK? I know it's very common, but I learnd that SK stands for "Sonnar Krasnogorsk". Am I completly wrong with this?

Best wishes - Guido

Hi Guido,

Really I don't know.
It seems evident that SK=ZK. Perhaps for Zeiss? Or Zorki? Or a problem of cyrillic drawing, the Z being a 3 ?

Someone must know!

Amitiйs. Jacques.

Hi,

I do possess Jupiter-3 #5104275 made in Krasnogorsk, as well as few lenses more: #5710589 (ZOMZ) and black one #6401395 (Optek?). Unfortunately not for sale yet, trade is possible ...

Regards,
Aidas

In Russian Sonnar is Zonnar, so ZK stands for Zonnar Krasnogosk.

Hello Vlad

Thank you for this explanation.

Best wishes - Guido

You're welcome Guido,

also, Jacques, Zeiss in Russian would be Tseiss, so if would've been "TS" letter - "TSK" then...

Vlad.

Thanks, Vlad.
And BK for Biotar Krasnogorsk, that sounds more evident!
So, no ZK to buy?

Jacques.
