Re: Not a bad lens, all the 60d/7d bodies are bad, or sensors anyway.

I recommend to you Photozone.de tests - they are quite reliable and consistent, also different bodies used. They are also explaining what they are doing.
I went to Photozone.de they have the exact same results. F8 is less sharp than wide open.
The guy on The Digital Picture seems to know what he is talking about. He said that the D60/7d is limited by defraction after F6.5 and after looking at photozone.de they show the same less sharp at f8 and that is on a 15mp 50d, see for yourself.

At f8 it's still well into the Excellent range and the corners are better.
If you're having problems MA your lens or GET A BETTER LENS. The sensor is not a problem.
