When I'm shooting indoors with any of my lenses on auto focus, I push the shutter down halfway to auto focus...it focuses but when I'm looking through the viewfinder it's still very blurry. When I go outside there seems to be no problem. I just got my 17-40 L today and inside it looks awful but outside it looks decent but not NEARLY as crisp as my 70-200 L. Thoughts on the focusing problem and the lens?
