i have this lens and LOVE IT, but currently my sigma 120-400 is on the milk carton.... ; AWOL.... ; unaccounted for.... ; where the heck is it?!
Tim, did you have to send it in for repairs? BTW, I see Sigma (Germany?) has posted their MTF for the new lenses....
don't forget it's stabilized as well. ; its an awesome lens and if i cannot find mine i will most likely buy it again. ; (and the 70-300 DO if i want to travel small).
