Leningrad question

If you look at post 1556 jlw answers that very question I posed a couple of weeks ago. Unfortunately mine was beyond repair and had to go back from whence it came :-(
 
I found the solution to this problem. However, I have another problem regarding the accompanied lens Jupitor 8. The lens seral number is 5517171. This lens seems not be used on any Zorki or Fed because it can not be focused at the infinity. The infinity indicated on lens just corresponds to 3m actually.

What's the problem? Does Leningrad have a difference imaging distance than Zorki or Fed? or this lens is not the original lens for Leningrad?

So I guess you have a good Zorki, that focuses good with other LTM lenses and this particular J-8 cannot reach infinity? Then the lens was messed up, because any lens in LTM mount should focus the same way on every LTM camera. (with some exceptions regarding FSU vs. non-FSU lenses, but this is FSU lens on FSU body and should work fine) Somebody took it apart and put it back together the wrong way... You will need to disasseble the focussing helical of the lens and put it back in another thread start. I guess you can find the "how to" at http://www.pentax-manuals.com/repairs.htm
