My camera does not focus. When I try to take a picture, things look very blur on the LCD screen. I cleaned the lens; however, that did not fix the problem. Interestingly, it appears that only when trying to take a picture of an object that is located very close to the lens, it will focus. Otherwise, it does not. It was working before, and I wonder what the cause is. Does anyone have an idea on what is going on? Thank you.
