AE functions is also possible.
Shutter-speed priority AE is especially useful
in action photography, aperture priority AE
in still photography. The programmed AE
mode, in which the camera controls both
aperture
and shutter speed for correct
exposure, is good for general use and is the
easiest mode for beginners. These three AE
modes along with exclusive flash AE, are
performed with an ED lens set at “A” for all
the benefits _ of full aperture metering.
Stopped-down AE, in which the shutter
speed is automatically set, allows automatic
exposure with non-FD lenses and accessories
and is a big advantage in close-ups and photo­
micrography. And since all AE inputs have
been consolidated into the AE mode selector
and the AT died, the operation of only these
two controls suffices to set the camera for
any one of the five AE modes.
For complete control for exposure cor­
rection or special effects, manual operation
is a simple matter of moving the FD lens
aperture ring from the “A” mark while the
shutter speed is set on the AT dial. The A-1
will even provide you with an exposure
readout as a basis for your exposure
adjustment.
