TTL METERING AND AUTOMATIC SHUTTER
For open-aperture reading, be sure that the stop-down lever is
DOWN.
After cocking the rapid wind lever, press the shutter release
button lightly to switch on the electric circuit. The meter needle
in the viewfinder indicates the correct shutter speed.
If the needle goes above "1000", close down the diaphragm until
the needle moves below "1000". If the needle goes below "1",
the shutter speed indicates an exposure longer than 1 second
.
The electronic shutter of the ES is guaranteed to work properly
down to 8 sec. (When making longer exposures with your eye off
the viewfinder, use the viewfinder cap to shield the light coming in
through the viewfinder as it may interrupt the correct exposure.
Caution: At slow speeds - slower than 1/30 sec. - support your
camera rigidly or use a tripod to prevent camera movement.
Depress the shutter release button completely when ready to take
your picture. When the shutter is released and your finder is off
the shutter button, the meter circuit is off and the needle will
return to the top of the scale.
