I bought the camera when they first released them and also bought the 70-200 2.8 L lens non IS. I have tried micro focusing the lens but still get no sharp images from it. I also at times while taking pictures it will totally blur then after pushing the button down a couple of times it will refocus and seem to act fine. It is set up on the center focus and almost all pictures taken in manual mode. All I take is pictures of my daughters and some of their sports activites. Any ideas what I should look at doing as far as should I send it in for Canon to look at it? I have a friend who has a older 20D and it takes ALOT sharper images than this thing does. Any suggestions will help.
If I understand you correctly, You have owned the camera and lens for two years, so you know best what to expect of the lens. If your other lenses do fine, and that one has troubles, sent it in for repair.
