Pros: Great at 100mm
Cons:
Loose as a goose and soft as a baby's butt at 400mm....

Well, I must have gotten the SOFTEST copy at 400mm that was ever produced (from B&H), because my images are really weak at that zoom level of 400mm. In fact I was just in Irvine, CA and dropped off the lens at the Canon Service Center for calibration at 400mm. To be honest, at 100mm the lens is tack sharp, but at 400mm, it is as if I am shooting with a softening filter. I am very disappointed in this copy of the lens.

Oh, and to be clear, I shoot with a 1DS Mark II, and my images through a 16-35mm or a 24-70mm are tack sharp with good clarity. My particular 100-400mm is garbage, and I hope that Canon either fixes it or replaces it under warranty!!!

Oh, and if I hold the camera facing downward, the lens will extend immediately to 400mm without any delay. It is loose as all get out too.

Understand that I love Canon products, but this copy of the 100-400mm is a lemon. It makes me pucker..... Will Canon fix it? We'll see what happens. Wish me good luck.
