Frame counter i
To keep track of the number of exposed frames, the frame
counter is graduated from two frames below 0 up to 40.
Blue numerals appear every 5 frames (0, 5, 10, etc.) with
dots in between. White marks at 12, 20, 24, and 36 indi­
cate the number of frames available on most film car­
tridges. When making blank shots with the shutter speed
dial set to "A," the shutter will fire at 1/80 sec. until the
frame counter reaches "1." In addition, the LCD shows
80 in the finder. Or if you set the dial manually between
1/125 and 1/2000 sec., the shutter will still fire at 1/80 sec.
In the finder, an “M80" is displayed. However, if the
speed is manually set to 1/80 sec. (X) or below, the shutter
will fire at the speed set and the speed will be displayed
by the LCD. Therefore, to speed up film loading, set the
dial to "A" or to 1/80 sec. (X) or above. "T" should not be
used when making blank shots as the shutter will remain
locked open.
