2. When the lens maximum aperture

blinks, the camera is warning that

A-TTL is impossible and the back
ground will be underexposed. The

posed correctly since normal TTL (see

p.18) functions instead of A-TTL.

•The maximum aperture value may

stop blinking when a slower shutter

speed is set: A-TTL is possible but be
careful of camera-shake.

3. When the lens minimum aperture

blinks, the camera is warning that

A-TTL is impossible and the back

ground will be overexposed. The main
subject, however, will be exposed cor

rectly since normal TTL (see p.18)

functions instead of A-TTL.

•The minimum aperture may stop

blinking when a faster shutter speed

is set: A-TTL is possible.
