(B) Aperture Priority Crossover AE Variation
This chart shows the pattern used by
the camera's microprocessor to
maintain the selected aperture for as
long as possible in relation to the
shutter speed, the lighting conditions
and the "camera shake" limit of the
lens in use.
When shooting bright scenes with
the 50mm lens at f/8, for example,
the camera maintains the preset
aperture until the fastest shutter
speed of 1/1000 sec. is reached, and
then varies to ensure proper
exposure as shown. For dark scenes
it holds to f/8 until the shutter speed
reaches 1 i30 sec. (the "camera
shake" limit for a 50mm lens). At
this point, it varies the aperture to
stay above the "camera shake" limit
until the maximum aperture is
reached, then shifts the shutter speed
to the next slowest speed in order to
assure a proper exposure. (For
exposures slower than 1/30 sec., a
tripod is required to prevent picture
blur).
The broken line indicates the
exposure pattern in the aperture
priority AE mode without
Crossover.
