Love the 24-85mm f/3.5-4.5 RS
I think you shouldnt miss 28-135 on A850 and perhaps 35-70/4.
But really I cant remember truly bad regular Minolta lens (only some zoom kits were bit iffy).
35-70 I still own. 28-135 is nice but heavy and the close focus distance is something terrible so I'd rather carry the 24-85mm personally. Like that lens though, really sharp and unique too.
