Hi, this is my first post on this site. I apologize that I write it in English but I am from Belgium and my German is rather lousy.
I came across this thread and I hope somebody can help me.
I had the luck to buy four of these lenses and I am planning to adapt one of them to my camera (a Sony alpha 7II).
For this purpose I am going to use an old beaten up Soligor 350mm f/5.6 lens that looks to be perfect for this.
That way I will be able to use the aperture of that lens as well, I reckon.
The only thing I would like to know though, that's the distance the lens has to have from the camera-mount at infinity.
Can anybody tell me this 'exactly'?
Thanks in advance for all the possible help.
