USE OF 577G ON CAMERA
WITHOUT HOT SHOE
The aperture found by putting this
guide number into the guide number
formula must then be set on the lens
by hand no matter what the camera.
Please note that the above equation
is only useful when all of the flashes
are placed close to the camera and
pointed straight at the subject.
* If a multi-flash setup is used with
a Canon AL-1 or AV-1 camera,
use a Canon Hot-Shoe Adapter
(optional accessory).
* When using the 577G with the
New F-1, A-1, AE-1 PROGRAM, or
AE-1, set the shutter speed at X-
sync or slower. Set the lens aper
ture manually off the “A” mark
using the guide number formula.
If the camera does not have elec
trical contacts for flash photography
in its accessory shoe, a synchro cord
must be connected between the
sensor and the camera for proper
synchronization. Available for this is
an optional accessory called Canon
Synchro Cord A. First make sure the
Transistor Pack G’s power switch is
off. Plug the two-pronged end of the
cord into the socket on the side of
Sensor Unit G20. Plug the other end
into the camera’s PC socket. For
setting the shutter speed and aper
ture, see “Other Cameras”, pp. 13,
15.
