From the 1970s, I have had Minolta cameras. I had an XD-7, and an XE, with a range of lenses, and when they were stolen, I built up almost the same collection again, with an XD-11 (the same as the XD-7 in a different market) and an X-700 (the last of the old manual-focus line). The lenses ranged from a 24mm f/2 to a 250mm f/8 mirror lens, all Minolta except the 24, which was a Vivitar. My favourite lens of all was the 85mm f/2 - I bought the first in Japan on a business trip, and made sure to replace it after the theft.
I never joined the Minolta autofocus boat, though I got my wife a Vectis S-1 (the APS SLR) which was a lovely camera.
I went electronic with the Minolta Dimage D-7, and later a Dimage A-2 (my wife had one as well). The best bridge cameras of their time, and a lovely lens (which never needed updating through the life of the range) - but the slow focussing and noisy images at low light levels just got to me in the end.
Then last Christmas I got my wife a Sony Alpha SLT-33, one of the new fixed mirror range (still Minolta in spirit, as Sony bought their camera business). It's a gorgeous camera, and she is very pleased. And I got myself a Sony NEX-5, which I am very pleased with; but the main limitation of the NEX range at present is that there are still very few lenses for it.
SO..., I just got a simple adapter to mount the Minolta MD lenses on the NEX, and all my old Minolta lenses are back in use (except the mirror, which I had sold, thinking I'd never use it again). The only thing lost over the old Minolta bodies is the automatic diaphragm - but as the viewfinder screen remains as bright stopped down, unlike an optical viewfinder, that seems no hardship. The focussing with a 7x or 14x magnifier is probably more precise than I could manage with the optical system. Because of the 1.5x multiplier effect of the APS-C sensor, the lenses all move up one place in usage, but that's fine, as the NEX has a 16mm (24mm equ) with a 12mm (18mm equ) converter). These are the old lenses I have (35mm equivalent on NEX in brackets):
24mm f/2 (36mm)
35mm f/1.8 (52mm)
50mm f/1.4 (75mm)
85mm f/2 (127mm)
135mm f/2.8 (203mm)
200mm f/4 (300mm)
Here they are, with the camera wearing the adapter (iPhone picture, as the camera is in the photo!):
