I've bought several MC and MD Minolta lenses for Alt purposes. Nothing expensive or elegant.
I can confirm that you will not be able to mound them and focus to infinity on any Canon EOS bodies, unless, as Michael said, you do a mount conversion (expensive), or use the cheapie tele-converter type adapters (not recommended -- I tried them, just to see).
That said, these Minolta lenses work great on M4/3 with a simple, cheap adapter (no glass). But when all is said and done, even there I mostly prefer my Canon FD 50/3.5 Macro, 24/2.8 and 35/2.8 lenses. Tried a Canon FD 50/1.4 and was blown away how sharp it was!
Unless you are going to use on mirrorless cameras, I'd avoid most of the everyday Minolta glass. Now, the 58/1.2 is another matter. . . for connoisseurs!
