Film Advance and Shutter Release
At the base of the film advance lever is the main switch of the camera. When it is at the “L” (LOCK) setting, all active circuits are turned off and the shutter button is locked to prevent unintentional shutter release. This switch should always be in the “L” position to prevent battery consumption and film wastage when the camera is not in use, such as when it is in a camera case.
When the main switch is set at “A”, the shutter button can be operated. The shutter button serves to activate both the AE meter and shutter operation. Since it is electro- magnetic, it requires only gentle pressure for both a very smooth shutter release as well as immediate meter response when shooting in quick succession. Pressing the shutter button lightly only halfway gives a meter reading preview inside the viewfinder. When you press it gently all the way, the mirror flips up, the diaphragm closes down and the
shutter releases. After shutter release, the mirror and diaphragm automatically reset and the film advance lever is ready to be advanced.
