Working below the metering range
If the camera’s metering range is not reached,
accurate exposure metering is not possible. Any
values that are then shown in the viewfinder can
lead to incorrect exposure results. For this rea-
son, if the metering range is not reached, the
warning symbol (2.1) appears in the viewfinder.
The LEICA R9’s metering system is extremely
sensitive, especially for selective metering. If the
warning display appears when the metering
method is set to center-weighted or multiple field
metering, you can often continue to work using
selective metering.
Full aperture metering
Most Leica R lenses are equipped with an auto-
matic diaphragm. This means that the viewfinder
image can always be viewed ast full stop, and
therefore with the maximum possible light, and
exposure metering occurs with the aperture
open. The lens diaphragm does not close to the
selected value until just before the shutter is
released, after mirror pre-release or the when
the stopping-down slider is pressed.
Stop-down metering
The PC-Super-Angulon-R 28 mm f/2.8 lens, cer-
tain earlier Leica R lenses and various accesso-
ries to not have an automatic diaphragm. With
these devices, the exposure has to be metered
with the set lens aperture, i.e. the stopped-down
aperture. In this case, the LEICA R9’s metering
cells receive more or less light when the lens
aperture is changed. With lenses and accesso-
ries with no automatic diaphragm, only the
modes
A or m can be used. The camera cannot
display the stopped-down aperture.
