Switching on the exposure meter
Turn the shutter speed setting dial to any value
between 1/2000 s and 4 s. Press lightly on the
shutter-release button [25] as far as the first
pressure point or press the locking button on the
selector switch [29]. When the LEICA R7's
exposure meter is switched on, the LED display
in the viewfinder lights up. If the shutter is
cocked when you release the button you have
used to activate the system, the LEDs continue to
light for about 12s. If the shutter is not cocked,
they extinguish at once.
Exposure metering at full aperture
Most LEICA R-Lenses feature an automatic
spring-back diaphragm. This means that, when
you take an exposure meter reading, a spring
opens the diaphragm to full aperture regardless
of the preset stop and then closes it again to the
required aperture setting for the exposure. When
using the following lenses, exposure metering
takes place at working aperture:
• PC-SUPER-ANGULON-R
f/2,8/28 mm,
• PA-CURTAGON-R
f/4/35 mm,
• TELYT-R f/6,8/400 mm,
• TELYT-R f/6,8/560 mm und
• TELYT-S f/6,3/800 mm
