I am having problems focusing. I get some "soft focus" or washed out shots with no focal point what so ever. My buddy even took my camera and tried it same set up as his. I endend up having to put my camera on more vivid today just to get good color that wasn't wahsed out and as far as focusing, it was hit or miss. Had to manual focus some shots. But if I was using my flash they were all focused. I was at a zoo using the 70-300. I ended up taking off my filter thinking it might be part of the problem. I know I have sensor dust also, could that have anything to do with it? I'm going to reset my camera settings to default and use automatic tommorow on a test then change them to what I usually use and see if that makes any kind of a difference. Can anyone add any insight on what might be the problem? I did drop my camera over a month ago, but it landed on the lens and didn't have any problems for the first two weeks, it was just last week this problem started comming up.
