Minolta SRT-101 mount same as Alpha?
Can you mount the old 35mm camera lenses on an Alpha camera?
Are they different than the Maxxum mount?
They are different. You will see references to MD and the older MC mounts. You're looking for the term "AF", "Maxxum", or "Alpha".
The cannot be directly mounted. Adaptors exist but, not surprisingly, focus and aperature control are manual.
