9 out of 10 points and recommendedPrice, build quality, image quality, fast focus and quiet.Could be a little faster. Not uasble on full frame bodies.
I am using this lens on a Canon 7D.reviewed November 20th, 2011 (purchased for $550)
Price wise this is a good value.
The lens is sharper than I expected.
I can get great images even at 1/60 second.
Easy lens correction in Lightroom 3.
