OPERATION OF CAMERA CONTROLS-continued
Self-Timer
The built-in self-timer can be used to trip the shutter after a delay of approximately 10 seconds, and it will operate whether the shutter speed dial is set for auto- matic or manual shutter speed selection. To take a pic- ture using the self-timer to fire the camera, first set the aperture and shutter-speed controls, advance the film, and cock the self-timer by turning its lever downward as far as it will go; then, simply depress the shutter re- lease button to start the countdown, with shutter re- lease occurring at the completion of the cycle (note that the mirror will rise as the shutter button is depressed and return at the end of the cycle). Note that the self- timer can be set either before or after advancing film; however, once cocked, it cannot be reset except by pressing the shutter release button. The self-timer may
not be used at the " B " shutter-speed dial setting.
Caution: Should self-timer operation be performed with the camera set for automatic operation, be sure that the finder eye- piece is covered to prevent the entry of stray light. Failure to do this can result in incorrectly exposed pictures.
Memory Lock
The convenient location of the self-timer lever, making for ready finger access, proves advantageous when using the built-in memory lock function. Memory lock enables the photographer to retain an exposure measurement taken close-up to the subject, or via selective composi- tion through theviewfinder, by "locking in" the reading taken prior to operating the lock. To operate the memory lock, view through the finder and meter on the selected area; then, simply push the lever toward the lens to hold the reading until the completion of the exposure. The reading will be retained as long as the control is held in this position. Thus, several frames can be exposed using the same locked reading. Also, the aperture can be adjusted without affecting the shutter speed locked in. (See "High-Contrast Lighting Situa- tions" on page 30 for details on the use of the memory lock function.)
