(7) USING THE BUILT-IN FLASH (ВТЕ)
With the Picutre Mode including the Green Operation
Mode or the Programmed AE. Mode in use
* The camera automatically chooses an optimum com-
bination of shutter speed and aperture according to
the subject brightness, allowing you to take a flash
photograph with ease. The shutter speed automati-
cally changes in the range of 1/100 sec. to a slower
speed which does not cause camera shake. The slow-
est shutter speed depends on the focal length of the
lens fitted to the camera. When a non-AF lens is used,
or the Action Program Mode is used, the camera uses
the shutter speed of 1/100 second.
* In the Programmed AE Mode, a shutter speed / aper-
ture combination can be changed by turning the select
dial. The Program-Shift works in the aperture range
that couples with a shutter speed of 1/100 sec. or
slower. For further details on the program shift, see
page 51.
Shutter-Priority AE Mode
The shutter speed can be changed in the range from
1//100 to a slower shutter speed when the built-in
flash is used. In the Shutter-Priority AE shutter speed
Mode, the aperture automatically changes according to
the ambient brightness, making the flash photography
easy.
Aperture-Priority AE Mode
To take pictures with a selected in-focus depth of field,
or change the distance to the subject, the flash can be
discharged at a desired aperture. In the Aperture-
Priority AE Mode, the shutter speed automatically
changes with the ambient brightness, making flash pho-
tography easy. The shutter speed changes in the range
from 1/100 sec. to a slower shutter speed which does
not cause camera shake. The slowest shutter speed de-
pends on the focal length of the lens in use. The shutter
speed of 1,100 sec. is automatically set when a non-
autofocus lens or the Action Program Mode is in use.
* When using the built-in flash in the Manual Exposure
Mode, any combination usage of the aperture and
shutter speed slower than 1/100 can be selected.
