So I'm aware that the 40d is know for having shutter problems, where the shutter "freezes" up intermittently. I don't think that's the problem I'm having, though. My camera seems to work fine, until I try to take a picture of something close up, like a flower or insect. The camera tries to focus, but cant unless I back up a little. But it refuses to take a picture until it completely focuses. This is SO frustrating! I want the camera to take a picture every time I hit the button, REGARDLESS of whether it thinks its focused or not. I'm starting to wonder if the only way I can take close up shots is with a macro lens. Or maybe a cheap close up lens?? Would that allow it to focus? What I would really like to do is to go into the settings and tell it to take a picture whenever the button is pushed, no matter what the conditions are. IS there a setting for this?? I am sincerely hoping that there is... I am shooting in Program mode by the way. Thanks!
