2. During TTL automatic flash exposure control, it
is impossible to use the Flash Exposure
Confirmation Lamp (AUTO CHECK) to check the
effective flash exposure control range in
advance. Instead, use the TTL Auto Flash
Exposure Control Coupling Range Charts above
or make sure the Flash Exposure Confirmation
Lamp lights for about 2 seconds immediately
after taking the picture.
