Sorry Marc, I didn't know they came that way. The two Hologon cameras
that I saw were both fixed focus, supposedly hyperfocal. Mine also
does not actually focus to infinity, but to some hyperfocal point
with a fairly small CoC. Hard to tell exactly where in practice. ;-)
It looks like you could grind down the stop that prevents it from
going to true infinity, but I never got around to it as it was sharp
enough for infinity at the stop, and I used it mostly for closeups in
later years. Then when I found out what people were willing to pay
for it, I decided that grinding any part of it down was not fiscally
prudent...
The Heliar has come to my rescue as a user, and without any grinding needed.
