I had (and sold) the Minolta 28/2.8 - it's just an okay lens. I don't know anything about the other two Tamrons, but the ratings aren't very high on dyxum.com. So if it were me, I'd pass on this set.
I can't afford ff camera right now so I thought to start up with film camera and build up my way with lenses first of all. I have an opportunity to buy locally a minolta dynax 7 with lenses that didn't get great reviews and I wonder if in practice they are any good. Opinions and links to images will be most appreciated.
The iffy lenses are Tamron 100-300 and Tamron 24-70. There is also a lens minolta 28 f2.8 that supposed to descent but its not a d or g lens.
