How autofocus operates
Infrared light emitted from AF port is used to estimate the approximate distance from the camera to
the subject. This information is used to roughly focus the image of the subject by moving the lens,
and then more precise focusing is conducted by the part of the CCD that receives the light from the
lens. When the subject is in focus, the AF correct mark in the viewfinder lights.
However, with some subjects, dark subjects or subjects of low contrast, the CCD may not operate
accurately, so focusing is conducted only with the infrared light emitted from the AF port. In this
case, the picture can be taken while the AF correct mark in the viewfinder is blinking.
