"Great with Rebel XT"4.0 starson by SAinCA
Pros: Light weight, very clear, decently fast focusing
Cons: Would like lower f-range, especially for indoor use w/out flash.
Summary: Very sharp images both with UV and polarized filters. Haven't noticed any untoward distortion throughout the range. Makes my XT very usable as a 28-320 where my old 28-300 (heavy by comparison) was much harder to use, i.e., keep stable, at long lengths.
