I am having problems focussing my Olympus C-770.
Sometimes when I try to take a photo it will not focus on what we're trying to take the picture of - other times it will.
I thought I may have been to close to the subjectbut even when I try at a further distance it's still the same. Mind you it doesn't happen to all my pictures just now and again.
Everyone has occasional focus problems. The camera is looking for contrasting edges somwhere in the scene. Sometimes it picks a focal point outside where the photographer intends. Many of us use spot focus mode to be sure the focus is where we want. If the camera doesn't give a focus lock indication in spot mode, try focusing on something at the same distance as your intended subject, and use half-press of shutter to lock the focus, and then reframe.
