Question about Canon EOS 40D Digital Camera
Manual focus works fine. Iv'e tried all my lenses and auto focus does not work. Trying to focus and the the lenses don't rotate automatically. I know it's not the lenses. Batteries are o.k.
I did some research on this problem and one of the things mentioned was that there may be a firmware update to address an autofocus problem with this camera.
Here is a page that may help you get the firmware update.
also another thing you may want to do to alleviate this problem is to reset your camera settings to the default setting and try it.
