10 SHUTTER10 ShutterThe New Canon F- 1 ’s hybrid shutter is electronically as well as mechanically con-trolled. Shutter speeds from 1/2000 to 1/125 sec., ” f ” 1/90 sec.) and ”B” (bulb)are mechanically governed, while 1/60 to 8 sees. are electronically controlled. Withthe AE Finder FN attached and the shutter dial on ”A,” shutter speeds from 1/1000to 8 sees. are electronically controlled.The shutter dial of the camera has settings from 2000 to 8, ”A,” ” f ,” and ”B.” Theslow shutter speeds from 2 to 8 seconds are in yellow, while shutter speeds from 1to 1/2000 sec. are in white. The white numbers are reciprocals of the true shutterspeeds; ”125,” for example, indicates a speed of 1/125 sec. Intermediate settings onthe dial cannot be used, and the dial cannot be turned between ”B” and ”A.”The red ”A” is for shooting in the aperture priority and stopped-down AE modeswith the Canon AE Finder FN attached. For this setting, pull up the outer ringand turn the dial until ”A” is aligned with the index on the finder. A scale withshutter speeds from 8 to 1/1000 sec. will now be displayed below the field of viewas long as the AE Finder FN is attached.The ” t ” setting is for synchronized flash photography at an X sync. speed of 1/90sec. It is not necessary to set the shutter dial to ” t ” when using a dedicated CanonSpeedlite; once the Speedlite’s pilot lamp glows, the camera automatically switchesto 1/90 sec. provided the shutter dial is not on ”B.”When the shutter dial is set to ”B,” the shutter will remain open as long as youpress the shutter button. The camera’s meter will not give a reading on ”B,” thusAE photography and match-needle metering are impossible. You will have to ex-periment or use a separate exposure meter to find the best exposure. It is advisableto use a tripod and locking cable release for long exposures.Since ”B” is mechanically controlled, the battery will not be drained on this setting19All manuals and user guides at all-guides.com
