I use it on a 5DIII...I was hesitant to buy a $1000 (when I bought it) lens that was made of plastic...but I there is no looking back...It is one of the SHARPEST (if not THE sharpest) lenses I own..(check my list ...that is saying something)...Just like justin...every time I shoot something with it ...I put the images up on the screen and I am bowled over with the sharpness...
Great lens..oh yeah...hey ...it shoots macro too, I am told!?!?!?!?! LOL!
