comment:For the money paid this lens is quite good.
The solid build and sharpness is fantastic.
The lens is also relatively light, when You see it You would expect it to be more heavy.

The problematic part is the slow AF speed. I tried it on A700 and the speed increased significantly (another reason of upgrade from 7D) :)
