Setting the correct shutter/aperture

combination

For correct exposure, check that the shutter

is fully cocked and the shutter-speed setting

ring is set to the required click stop. Acti-

vate the exposure meter. Turn the shutter-

setting ring on the camera and/or the aper-

ture-setting ring on the lens until the round

middle LED in the viewfinder's shutter/

aperture balance lights up. The two arrow-

shaped triangular LED's in the viewfinder

shutter/aperture balance indicate under- or

overexposure and show the direction in

which either setting ring should be turned

for correct exposure, as follows:

underexposure by at least one f/

stop; turn clockwise;

underexposure by half an f/stop;

turn clockwise;

correct exposure;

overexposure by half a stop; turn

anticlockwise;

overexposure by at least one f/stop;

turn anticlockwise

Metering at full aperture

LEICA R-Lenses are equipped with an

automatic spring-back diaphragm. This

means that, when you take an exposure-

meter reading, a spring opens the dia-

phragm to full aperture regardless of the

preset stop and then closes it again to the

required aperture setting for the exposure.

Working-aperture exposure metering

Some lenses and accessories do not have an

automatic spring back diaphragm or lack the

linkage mechanism for it. This applies, for

example, to lenses with adaptations for

balancing the angle of view or those with a

long focal length, e.g. the quick-focusing

lenses TELYT-R f/6.8/400 mm and f/6.8/

560 mm. In these cases, you have to obtain

the exposure-meter reading at working

aperture, stopping up or down to adjust the

amount of light reaching the exposure

meter's photocell.

Important!

To prevent wrong exposure values, do

not press the depth of field lever while the

exposure meter is in use.
