I'm looking for older autofocus EF mount zoom lenses. Specifically ones with low contrast and low to medium sharpness and if it has a tendency to flare all the better. No need for them to necessarily be Canons, aftermarket manufactures are fine as well (maybe preferred..) I'm assuming the first generation lenses (late 80s to early 90s) are my best bet and I've seen the canon 35-70 mark I but have heard mixed reviews as to its performance (I'm looking for low performance!) And I know about the canon 28-80 as well. Both of those fall right around the zoom range I'm looking for but I'd be particularly interested to hear any other suggestions. And, as a matter of fact, I'd love to hear about any telephoto zooms that meet these criteria as well.
