Canon EF, Инструкция по эксплуатации

Страница: 41 / 68

•
When using the CAT System with the EF camera,
the shutter speed dial must be set at" 125," the CAT
switch set to the " " position, and the aperture ring
set at the 'A' mark. With all other types of
flash, the switch may be left at its "NORMAL"
position, but the aperture ring has to be set
manually.
•
At present, the CAT System may be used with
four Canon lenses: two standard 50mm lenses, the
f/1.4 and f/1.8 and two 35mm wide-angle lenses, the
f/2 and f/3.5.
•
Normal AE photography may be performed at
any time when using the CAT System by returning
the CAT switch to the "NORMAL" position.
•
Two electronic flash units, one direct-mounting
type inserted in the flash hot shoe and another using
a PC cord plugged into the sync terminal, cannot be
used simultaneously on the EF. When a PC cord is
plugged into the sync terminal, the flash hot shoe is
automatically disconnected.
•
After using the CAT System for flash photography,
turn the camera off and return the CAT switch to
the "NORMAL" position. If you leave the switch
set to the position and turn the camera back on,
the automatic exposure setting for your next flash
shots will be incorrect.
