Minolta 70-210mm and 28-85mm.....dilemma......what to do with them

Yes sell them. The 28-85 lens is much heavier than modern designs and to me the 70-210 F4 is over rated. Also auto focus is much slower than current lenses due to weight of glass and metal barrels to move. I had both from mid 90's to replace power zoom kit lens on 700si and sold them when I got my Maxxum 7 in 1999. The 24-105 and 100-300 lenses which replaced them were same or better image quality and focused much faster.
