If we're talking Minolta AF, then I've found most rather disappointing. I'm not talking about APO or SSM expensive Minoltas, just the average lenses. The beercan was slow, CA was shocking and not that sharp for me, the 100-200 f/4.5 was slightly better but just equal with a modern Tamron 70-300 macro (the cheap one). The 50mm 1.7 just loved flare and seemed to find the smallest amount of light to produce flare, imo the cheaper Sony SAM 50mm 1.8 is better. The cheapest Minolta AF I ever bought was a 35-70mm f/4 and that was actually rather nice to use, although very restricted on APSC.
I always cringe when people on Dyxum talk about their 28-80 having '"Minolta colours" and only the "Mind of Minolta" could create such lenses. It seems a lot of hysteria has been built about older, average Minoltas.
... I feel like a bad Sony user for speaking out about Minolta, so I'll end with my praise for my little trio of Rokkors I used to own.
