Hi fellow rangefinder users, I seem to be having a problem with my Zeiss Biogon 2/35 ZM. It doesn't seem to focus to infinity at wider apertures. I just did a shot at f/2 where I focused to infinity (on the lens - not with the rangefinder) that would render sharp everything up to about ten meters (30 ft), and from thereon things started to be blurred. Distand objects weren't sharp at all. It generally doesn't seem to focus correctly from 5 meters on at f/2. I have no problems at closed apertures, since I guess there d-o-f compensates for this issue, and the lens is also spot on at shorter distances at the wider apertures. Has this occured to anyone? Is this typical for the Biogon? Or do I have a flawed copy? Mind that this doesn't bother me much, but if it could be corrected, that would be nice 🙂 P.S.: I posted this here as I am shooting the lens on an M8 - but if this thread should be moved to the Zeiss Ikon forum, please let me know.
