The B setting/Turning off the exposure meter
With the B/OFF setting on the shutter speed
setting dial, exposures of any duration are pos-
sible. The shutter remains open for as long as the
shutter release button is held down, but the expo-
sure meter is switched off by this, though.
If the camera is not used or is stored in a bag for
a long time, it should always be turned off by turn-
ing the shutter speed setting dial to the B/OFF
position. This prevents any power consumption,
including the low consumption that continues to
occur in standby mode after the exposure meter is
turned off automatically and the display is extin-
guished.
Exposure meter metering range
At room temperature, normal humidity, and an
aperture of f/1.0, the metering range stretches
from 0.03 to 125000cd/m
2
. At ISO 100/21°, this
corresponds to EV -2 to 20 or f/1.0 and 4s to f/32
and 1/1000s (see also diagram on p. 99).
Working below the metering range
If you are below the exposure meter’s metering
range at very low light densities, the left-hand
triangular LED flashes as a warning.
Since exposure metering takes place with the
working aperture, this situation can also be creat-
ed by stopping down the lens.
Even if you are below the metering range, the ex-
posure meter remains on for around 14s after you
let the shutter release button go. If the lighting
conditions improve in this time (e.g. through a
change in the subject detail or opening of the
aperture), the LED display changes from flashing
into being continuously lit, indicating that the me-
ter is ready.
