How do you tune the 40D with the lens??? Is it doe by Canon??Thanks
It is done by Canon. I discovered this when my Xsi took outstandingly crisp photos with the same lens that was very mediocre on my 40D. I researched on the web and found folks talking about. I sent the body and lens to Canon (the body was under warranty so they covered shipping and the procedure) and when it came back I was thrilled. It was just as sharp as the Xsi, perhaps even sharper. Then I knew that all those folks selling their lenses because they got a soft copy might just have needed Canon to do their magic...
Perhaps there is a way to get a good price on someone's soft lens... ;-)
