Special Controls
TIME EXPOSURES are made by setting the shutter to B - the shutter will remain open as long as the release is depressed.
Use a cable release. See the chapter on "Exposure".
FLASH SYNCHRONIZATION. The shutter is XM synchronized and is set to the X or M position by pushing the lever
(with yellow head) behind the aperture thumb wheel to the engraved X or M. See the chapter on "Flash".
SELF-TIMER (delayed action release). This permits the photographer to appear in the picture. Place the camera on a
tripod or other rigid support. Set flash synchronizing lever to X and push down the delayed action lever (with red head) on
the base of the shutter as far as it will go. On pressing the shutter release, the shutter opens after a delay of approximately
10 sec. The delayed action can be used with all speeds from 1-1/500 sec. If set to B it will release but gives a speed of
approximately 1/60 sec.
It can also be used with flash shots, but only with X Synchronization.
