The three zooms that I've used that out perform most of the primes I've
used are the Vivitar 3S1 5-85mm varifocal, and the Vivitar S1 90-180
flat field, and the prosumer smcp F 70-210 4~5.6. The Vivitars were
quite expensive when they were new and very sharp suffering only from
increased flair when compared with almost any other lens I've ever
used. I don't use them as much as I used to because they aren't A
lenses. They were rather slow working lenses when the were supported by
open aperture metering. I'm especially looking forward to seeing what
the flat field lens does on the K20D. I'm expecting very good
resolution and sharpness to compensate for the lack of OA metering.
