I have an opportunity to buy Minolta Maxxum 50/1.7 and 28-85 for $50 together. According to the seller they are in great shape. I used to have 50/1.7 briefly, while it's a great lens, SEL50 is better in most areas. Don't know anything about 28-85, looks like it's fairly large and heavy and not as good optically as 35-70. Anyone knows anything about this lens ?
