Since the F-1 has an interchangeable viewfinder, it is
not equipped with a built-in hot shoe. Canon offers two
accessory hot shoes which slide into the guide rails at the
base of the F-1's rewind knob from the back of the
camera. Flash Coupler D is a simple hot shoe for direct
contact flashes. Flash Coupler L is a hot shoe which also
has special contacts for semi-automatic flash with the
Canon Speedlite 133D using the Canon Auto Tuning
(CAT) System. This coupler is also equipped with a
lamp for illuminating
synchronization cord of a flash which lacks a direct
contact must be branched to the F-1's PC socket.
Flash photography is possible with the CAT System
using the Canon Speedlite 133D, the Canon FD 50mm
f/1.4 S.S.C., FD 50mm f/1.8 S.C., FD 35mm f/2 S.S.C.
or FD 35mm f/3.5 S.C. lens and either Flash Auto Ring
A2 or B2, depending on the lens. After Flash Coupler
L is locked into position by pushing its lock lever
upwards, the Speedlite 133D may be slipped into its hot
shoe from the rear. The appropriate Flash Auto Ring
should then be mounted on the front of one of the
four above lenses and its cord connected to the flash.
The Flash Auto Ring relays the shooting distance to the
camera meter. Proper exposure is obtained by matching
needles as usual after the shutter speed has been set to
the synchronization speed of 1/60 sec. and the Speed-
lite's main switch to AUTO.
