Digital
Camera: AF Sensor Location
Autofocus in digital
cameras is affected by where the AF sensors are located. When several
sensors are in a group and located in the image area it is easier
to target the focus on the intended subject in the overall scene.
Advanced digital
cameras may also have variable sensing so every possible subject
in the entire scene can be detected. When using less expensive cameras,
the photography will have to do more work to help the camera find
the subject to focus on. This is done by moving the camera slightly
so the subject is more easily found by the sensor.
