Canon EOS 620 - 650 camera manual
5. Comparison between AF Mode and Film Winding Mode
(in the evaluative metering mode)
6. Program Line (program characteristics)
This camera is equipped with the advanced "Intelligent Program AK" which chooses the best
shutter speed/aperture combinations, taking the lens focal length into account. When the
automatically-set shutter speed becomes O to 0.5 steps below 1/focal length of the lens in
use, the camera-shake warning sounds. The shutter speed of 1/focal length of the lens is
generally said to be the limit for hand-held shooting.
