9 out of 10 points and recommendedsharpness, color practically everythinglens creep, hood and cap problem as usual.
A friend of mine urged me to try this lens and the tamron 28-70mm. The latter was out of stock so I decided to test this instead. 1st few shots and I was amazed by the color it produces that I had to buy it right away. 2 of my friends sold their 17-40 L lens and swtiched to this sigma so when I had extra money I had this in mind. No regrets. This lens delivers and makes my vr lens look baaad!!! IQ is at par or even better than one of those trinities.reviewed April 25th, 2007 (purchased for $500)
My only gripes are lens creep and the hood and front cap. Man this has always been the problem of Sigma. once you put the hood its so hard to put the lens cover back. you have to take off the hood 1st to put on the cover arghhh Hope next time it wont be an issue anymore.
Bottomline this lens is a winner. Highyl recommended
