4-4 Long Exposure Photography
The longest nominal shutter speed of the Bronica RF 645 is eight full seconds. If a longer exposure is required, set the shutter speed dial on bulb ("B"). The electronically control shut- ter system of this camera stops consuming battery power one second after the shutter click in bulb operation in order to conserve the battery. Still, it is strongly recommended to carry backup battery cells if repeated long exposures are anticipated.
Note 1: The viewfinder LCD displays "BUL" as the shutter dial is set on "B".
Note 2: Never try to remove the lens from the camera during a long exposure.
