I'm not experienced at testing lenses, but I did take a few sample pictures under semi-controlled conditions. They were taken on a firm tripod using mirror lock-up and a remote release. They aren't the best, but they do show some of the capability of this lens. These are 100% crops. No editing at all, except to save as jpg. The concrete wall should be in focus.
This one is at 300mm, F2.8, ISO100, 1/200sec.
This one is at 300mm, F11, ISO100, 1/13sec.
Sorry I don't have better samples, but I haven't had time to really use it yet. I think both of these are acceptably sharp, though a little less sharp than, say..., my 50mm F1.4. I think with a touch of USM, the F11 sample would be exceptional, and the F2.8 version would be very useable.
I'm sure everyone will dissagree.
