SK 135 4,0 from 1948

Hello to all,

this nice lens arrived today, a SK 135 4,0 from 1948 with serial number 000512. It looks real to me, what do you think?

Some pictures compared to a 1970 Jupiter 11. The SK is on the left side:







And some details from the digits of the SK:

Excellent condition! the diaphagm numbers are typically Zeiss!
The focus cam made in Russia!
a very low number!

Hello Ulrich,
very nice lens. I have the next one "ZK Zorki 1:4/13,5cm" also with Sonnar parts. It seems to be from 1950.

Thank you Ulrich and Alexander for sharing. I have never seen so early Jupiter 11.
I can see cypher "3" in "30" on distance scale is complitely different.

Alexander,
a nice lens with nice serial number. Do you know how to open the lens? I want to see the Zeiss number on it to find out when the glass was produced. Normal J-11 opens easy, just grab the front part and screw it off. On the early SK lens this seems not to work. Is it just too tight or do I have to loose a crew?

Alfa,
other digits are different too. Both of the 4 (on diaphragm and focus scale) are different to normal J-11.

Luiz,
yes, it has a nice number. I like the 512 :-)

Yes, Zeiss digits are more slim.

Dear Ulrich,

the upper lens part can be fixed by a screw. It is better to unscrew the curled ring with the engravings of aperture settings and then inspect where is this hidden screw. Zeiss LTM 135 Sonnars usually have this screw. My SK 135 4,0 from the same year as yours does not have it.

On my SK there is no Zeiss number. However, I have no doubt that the lenses there are from Jena.

with best regards
altix

Altix,

thanks for the hint. I have removed the ring, there is a screw. But unfortunately the head of the set screw is damaged :-/ Seems that somebody else tried to open the lens and damaged the slit of the screw.
