EXPOSURE
The readiness of the exposure meter is signaled by continuously lit
displays in the viewfinder or on the screen:
the shutter speed is displayed in aperture priority mode
one of the two triangular LEDs lights up in the viewfinder,
possibly in conjunction with the round LED in the middle, and
the light balance is shown on the LCD panel for a manual setting
The exposure meter is disabled when the shutter speed setting
wheel is set to B.
EXPOSURE METERING METHODS
Optional methods are Spot metering, Center-Weighted and
Multi-Field metering.
SPOT METERING
Spot metering only captures and analyzes a small area in the
middle of the screen image, which is shown in a circle.
CENTER-WEIGHTED
METERING
This method considers the entire image field. The subject elements
captured in the center will, however, impact on the calculation of
the exposure value more so than areas around the edges.
MULTI-FIELD METER-
ING
This metering method is based on the detection of multiple values.
These values are used in an algorithm to calculate an exposure
value appropriate for a good rendering of the assumed main
subject.
WHEN USING THE RANGEFINDER
Mostly center-weighted metering.
The light reflected by the light-colored shutter blades is captured
and measured by a photodiode. When the measuring range of the
exposure meter is undercut in a manual setting and very low light
density, then the triangular LED (
) in the viewfinder on the left will
flash as a warning; the LED on the right ( ) will flash when the
measuring range of the exposure meter is surpassed. The shutter
speed icon will flash as a warning if a correct exposure cannot be
achievable using the available shutter speeds in aperture priority
mode. The relevant icon will flash if the required shutter speed
would undercut the fastest possible shutter speed or overshoot the
longest possible shutter speed. As exposure metering is done with
the working aperture, the same can be achieved by stopping down
the lens.
IN LIVE VIEW MODE
Optional methods are Spot metering, Center-Weighted and
Multi-Field metering. The metering will then be done via the picture
sensor.

The set metering method is displayed in the header of the
display image in Live Mode; it appears on the status screen
(see p. 46) if the viewfinder is used.
