competitive price six year warranty good low light focus quiet .

slight noise at 300mm but that can be corrected with my software so i feel it is a good trade off for the price when compared to othre lenses .

I am extremely pleased with this lens at the price it is hard to beat. The color is excellent the focus is crisp and clear with my canon 20d.
I have found this to be a reliable and extremely well made lens for use with the canon 20d .

Small and light, wide zoom range, good 28mm wide angle

Very poor at anything over 150mm zoom range.

Its an ok lens, but its not very good over 150mm where its almost always blurred. I took mine back, swapped it for a Canon.
