EXPOSURE METERING

In this camera, the exposure is metered for the available ambient
light though the lens with the working aperture with strong center
weighting. The light reflected by a bright shutter diaphragm blade
in the first shutter curtain is measured. The time/aperture combi-
nations suitable for the correct exposure are indicated by the
viewfinder displays or identified with their help.
In aperture priority mode, the aperture is selected manually, how-
ever the camera forms the shutter speed automatically. In this
mode a digital LED display provides information on the shutter
speed to be used (e.g.
A light balance (▸▯◂) comprising three red LEDs is used to adjust
the exposure for manual settings. If the setting is right, only the
central, circular LED lights up.

Turning the exposure meter on/off

The exposure meter is switched on by lightly pressing the shutter
release button down to its 1st pressure point, provided that the
camera is switched on with the main switch and the shutter speed
dial is not set to B. The readiness of the exposure meter is signaled
by the constant lighting of one of the displays in the viewfinder:
– in aperture priority mode the digital LED display of the shutter
speed,
– and in manual mode one of the two triangular LEDs lights up,
either individually or in conjunction with the center circular LED.
If you let go of the shutter release button without activating the
shutter, the exposure meter remains turned on for around 12s
more, and the relevant LED(s) remain lit for the same time. If the
shutter speed setting dial is set to

Notes:
• When the displays have gone out, the camera is in a "stand-by"
mode.
• In very low ambient light, i.e. at the limits of the exposure meter,
it can take around 0.2s until the LEDs light up.
• In aperture priority mode, if correct exposure cannot be
achieved using the available shutter speeds, the shutter speed
display gives a warning by flashing (for more details, refer to the
"Aperture priority mode" section on p. 83).
• If the exposure meter reading is below its working range in very
low lighting conditions and in manual mode, the left hand trian-
gular LED flashes as a warning. In aperture priority mode, the
shutter speed is still displayed. If the required shutter speed falls
below the slowest possible setting of 60s, this display also
flashes.
• If the camera is out of use for an extended period or is stored in
a case, always turn it off at the main switch. This prevents any
power consumption, including that which continues to occur in
standby mode after the exposure meter is turned off automati-
cally and the display is extinguished. This also prevents pictures
from being taken accidentally.
The appropriate shutter speed for correct exposure, or the varia-
tion from a correct exposure setting, are specified or determined
using displays in the viewfinder (see following sections).
