"100X": This setting is provided mainly for mechanical flash synchronization at 1/100th second for flash units which do not offer automatic flash synchronization (see Page 31). Since the shutter operates without batteries at this setting, it also permits you to continue operating the camera in case of battery failure. If the batteries fail, set the dial to "100X" and adjust the lens aperture according to the subject brightness (refer to the exposure guide lines accompanying your film.) B "B" (Bulb): This setting is for long exposures exceeding the 1-second maximum shutter speed of the camera's electronic exposure system. Time exposures lasting several minutes or hours can be made at this setting (see "TIME EXPOSURES AT "B," Page 25). 1OCX B **4 15 •
