Well, if i'm mistaken, it still works. I even put a beercan lens on my a-700 (with no adapter) before I posted just to make sure I was right, and it mounted fine, and focused fine. Altho, it IS manual focus etc.
The 1mm difference in flange distance has not caused me any problems.
You might check: https://en.wikipedia.org/wiki/Minolta_SR-mount for more specifics, and also the entry for the Sony A-mount.
The "beercan" lens is an A mount lens , the Minolta 70-210mm f/4 that was released in 1985 with the Minolta 7000AF .
It's an autofocus lens who's optics were borrowed from the earlier Minolta SR mount ( manual focus ) 70-210mm f/4 lens .
The lens refered to as the "beercan" does not fit on any manual focus SR mount camera .
And likewise no manual focus SR mount lens will fit on an A mount body , be it Sony or Minolta .
My first DSLR was the Sony a100 in 2007 so I could continue to use my Minolta A mount lenses from my Minolta 7000AF I bought used in the early 1990's .
I also have most of the manual focus SR mount Minolta cameras and a good selection of SR mount lenses .
Pre MC lenses , MC lenses and MD lenses .
Non fit on Minolta or Sony A mount cameras without an adapter .
The mounts are physically different, it's not just the registration distance that's different .
Do a search on it , or do you need me to post a picture of the two lens mounts together?
