Minolta lenses are very good; there was a time when they designed lenses for Leica as well.
Minolta G lenses are (close to) as good as best of L lenes --- L lenses may have good or not so good ones for different price range, but every G lens is very good (not sure about sony version). now you can plus Zeiss into their side.
it was MF era when Minolta worked with Leica, toooo long ago.
it would be a dream team if Leica/Zeiss/Minolta/Sony work together to produce a set out
canon may feel great threat
