142 / Exposure meter metering range/Working above and below the metering range
Exposure meter metering range
The metering range at room temperature, normal
humidity and ISO 160/23 is EV 0 to 20 or f/1.0 and
1.2s to f/ 32 and
1
/
1000
s.
Working above and below the metering range
In poor lighting conditions when using manual mode,
if the reading is below the exposure meter range, the
left hand triangular LED gives a warning by flashing,
and the right LED does likewise in excessively light
conditions. In aperture priority mode, the shutter
speed is still displayed. If the required shutter speed
is below or above the slowest possible speed of 32s
or the fastest possible speed of
1
/
4000
s respectively,
these displays also flash.
As the exposure is metered with the working aperture,
this situation can come about by stopping down the
lens.
Even if you are below the metering range, the expo-
sure meter remains on for around 12s after you let go
of the shutter release button. If the lighting conditions
improve in this time (e.g. through a change in the sub-
ject detail or opening of the aperture), the LED display
changes from flashing into being continuously lit, indi-
cating that the meter is ready for use.
