Shutter re.e••e button ® The shutter release button also serves to activate the FM2's built-in exposure meter. When the film advance lever is in the flush position, the shutter release button is locked and will not operate. To release the button from its locked position, pull out the film advance lever to the standoff position. Slight pressure on the shutter release button will then switch on both the exposure meter and the LED exposure information display inside the viewfinder. The meter and the display remain on for approx. 30 sec . after the finger is removed from the button, after which they are automatically switched off to conserve battery power. Pressing the shutter release button all the way down releases the shutter. When you depress the button , touch the fingerguard ® with the tip of your index finger and depress it lightly with smooth, even pressure. This makes shutter release operation smooth and stable. With a shutter speed of 1/30 sec. or slower, it is advisable to attach the camera to a tripod and use a cable release to release the shutter; this will prevent camera shake which results in blurred photographs. The cable connector can be screwed into the hole at the center of the shutter release button. If the tripod has a large head, contact between the lens barrel and the head may make it impossible to turn the lens aperture ring . In this case, use ,he special tripod adapter supplied with the camera between the tripod head and the camera body. 17
