2 5e r .°a • AteO Shutter Release Once you have focused, composed your picture and confirmed correct exposure, gently press the shutter button all the way down to set the shutter in motion. When the shutter is released, the exposure will be stored. so there is no problem in removing your finger from the shutter button even in the slow speed range. If you press the shutter button in one very quick stroke, the viewfinder display will become invisible and the camera's function may be delayed for an instant, but exposure metering will not be affected and your picture will be accurately exposed. If you press the shutter button with an extremely quick punch, it is possible that the shutter will not be released at all. For proper function and the least camera shake, it is best to press the shutter button gently. To cancel shutter release, press the battery check button or return the main switch to "I.". Shutter release WILL. NOT be cancelled in the slow shutter speed range simply by turning the Al' dial to a higher shutter speed. Pressing the shutter button will not make an exposure if the film is only partially ad• vaned or if battery power is too low. Rewinding the Film When you have reached the end of the film. the film advance lever will stop suddenly before the end of its stroke. DO NOT force the film advance lever beyond this point or the film may become detached from the cartridge or tear, making rewinding impossible and necessitating handling the film in total darkness or a changing bag. Also DO NOT open the camera's back cover before rewinding or your film will be totally exposed. -58-
