Anyone had experience of the
Sankyo Kohki Super-Komura "Uni Auto" 300mm f5.0
I have one that never quite seems to get into proper focus, at any distance or any aperture,
though (as might be expected) the problem is somewhat less blatantly evident at f16 or f22.

The lens is in good condition and does not appear to have ever been adjusted or dismantled.
It has a rather neat interchangeable lens mount marked "Komura Uni Auto SP".

I've had two of these and both were disappointing.
One worse than the other.
A pity, they seem like they should be decent, others in that line are quite good.

There were two separate interchangeable mounting systems used on these. The earlier series was meant for use on a Leica Visoflex-type reflex system; for use on proper SLR's mounting tubes for different SLR mounts were available. Later ones used the later Komura interchangeable mount systems.
