Frame Counter
The frame counter operates automatically to show how many frames have been exposed. When the camera back is opened for loading, the counter is reset to the " S " (start) position, two frames before " 0 . " Once the camera is loaded and the back closed, each film- advance/shutter-release sequence will cause the frame counter to advance one position until the maximum 20 or 36 frames have been exposed. The dial of the frame counter is calibrated with dots (for odd numbers) and figures (for even numbers), and with settings of "S," "20" and "36" in red.
Shutter Release Button Lock
A special control is fitted around the base of the shut- ter release button to provide for greater ease of opera- tion when using the EL2 with the Auto Winder AW-1 mounted for automatic film advance. With the shutter release button lock, the film-advance lever's meter ON/OFF and shutter button lock functions are dupli- cated to enable positioning of the lever flush to the body while using the Auto Winder. To operate the camera via the shutter release button lock, simply switch the lock to the left to reveal the red meter ON index; in this position, the meter is on and the shutter button is unlocked for normal release operation. When not using the Auto Winder, switch the lock back to the right and operate via the film-advance lever.
Note: Whenever the camera is stored, be sure that the shutter release button lock (as well as the film-advance lever) is set to the "meter-OFF" position to ensure against accidental battery drain.
