Q&A: Autofocusing With Filters

I have an Olympus C-3020. I plan to buy a filter adapter for it so I can use the close-up lenses from my old 35mm days. Will the camera autofocus with these in place?

Indeed, Charlie, most digital cameras have no trouble at all continuing to autofocus even with additional filters or lenses placed in front of the built-in lens. Likewise, the exposure meters work like a charm as well. Keep in mind, though, that close-up filters will put you so close to the subject (within a few inches) that the optical viewfinder will be useless. You'll have to position and focus the camera using the LCD display.
