If the subject is too bright or too dark, both I shutter speed and aperture
value indicators will blink and will show limit values. If the subject is
too bright, use an ND filter to reduce the brightness. If the subject is too
dark, use the flash.
You can change the combination of the shutter speed and aperture value
selected by the camera. If you turn either the S-Dial or the A-Dial, the
combination of the shutter speed and aperture value will change within
a range of combinations which give the same exposure. The Program
Shift will reset the exposure if the camera has switched itself off or if
the mode dial is turned away from the P position.
For example, when you use the 28-70 mm F2.8 lens and the camera selects 1!125 and F8, you can shift to any
of the following combinations, all of which gives the same exposure.
