now all the Sony users have cottoned on that the old Minoltas work.
Not strictly true.
While the fitting is the same, not all Minolta fit lenses will work with Sony cameras. It's to do with the electronics and whether the lenses and camera body can communicate all the right information.
This did interest me as I already have a Minolta Dynax film SLR, so getting a Sony camera that could share lenses would be good.
But apparently it's a bit hit and miss.
