Hi
I am planning to get a Jupiter 3 for my Kiev and based on previous experience I am almost sure I will have to adjust the focus (backfocus, camera working distance.. whatever you call it) once it arrives. I have done this on a 50s J8 before and I am wondering whether the process will be as easy on a J3. I have never held a J3 before and I count not find any repair info on the internet. Not the Kiev mount one at least.
AND Is there a difference between the previous and later models? I know they are made in several factories over the years. The one I am looking now is an early 50s model.
Thanks
Berk

Thanks Brian.
However, on the early J8 I worked on (Kiev bayonet mount) I just had to loosen the little screw on the lens mount and rotate (re-position) the lens mount until the lens focused right. Then I lined up the aperture markings by loosening the three little screws on it and setting the aperture nubmer dial in place. Maybe I did not do it the official right way but I dealt with no shims etc.
Maybe this is not a luxury with LTM mount lenses but I am wondering whether I will be able to do it on the Kiev mt. J3 as well. If I have to do bigger work I will skip this lens. I do not have extra shims.
