Review title: CRAP.
Product review: Seriously. Right out of the box I was impressed. It came with a lens hood, bag for the lens and it really made you feel like you bought quality. I attached it to my camera and right away I noticed vignette, back focusing, noisy focusing and over saturation. I could have gotten a bad copy but, it was enough to make me send it back that day. This is my personal experience. I'm not saying all SIGMA 70-300s act this way.
