After an analog and manual Minolta camera set fell into my hands, I purchased an F-mount to Minolta SR converter without and with correcting glas to use the lenses on the Nikon D7200. The plain adapter ring limits the focus ability up to a certain distance, depending on focal range. It’s OK for macro and portrait photography. The latter should sustain focusing to infinity. My objective was to revive the collection for occasional use that create a little retro-style picture mood – and to practice the handling for analog shooting.
Let me spoil the result: it doesn’t make much sense.
The Nikon DSLR was still not able to focus to infinity, which was very disappointing. Maybe the copy of my converter was faulty, but I will not make any more effort. Reason is, that it just is not feasible. Focusing manually was very difficult as the only support you can rely on through the viewfinder are the small arrows and the dot at the viewport bottom that indicates where to go. It takes me ages to focus and I often miss.
Also, at apertures wide open e.g. with the Minolta 50mm f1.7, pictures are useless as the appear to glow and are soft. Might be some reflexions within the lense/adapter/body volume that do not occur for f2 and above.
I think, you’re way better off using a full frame or APS-C mirrorless body with all the advanced digital support like focus peaking and WYSIWYG. Maybe the Sony Alpha 7 or the Fuji XT-20.
Annyway, here are some pictures.
