Hi, everyone.
This is my first posting on this forum.
It's good to see you all.

I have used KIEV 4 for about a year with Jupiter-8, 9 and 12.
I satisfied with Jupiter-8 and 9 but not with Jupiter-12.
I can't focus well with the Jupiter 12 at f5.6 and lesser.
First time I thought it's maybe because my KIEV 4 camera (1973) and my Jupiter-12 (1959, Silver) are not a version.
So I bought another Jupiter-12 lens of later year's (1977, Black).
But it also was not well fit in focusing with my KIEV 4 camera.

Should I buy another version of Jupiter-12 or send to repair?
I will deeply appreciate about any advise about this.

Thank you to read this text and I hope you to forgive my broken english.

Hi,
If the J8 and J9 are working correctly, it is likely to be the J12 lens. It would be better to get this collimated and the shims adjusting so it works.
