Exposure metering
The LEICA M6 TTL meters for exposure under
ambient light through the lens at the working
aperture. The reading is selective, by light
reflected from a bright metering field onto a
photo diode (arrow). This diode is located
behind a collecting lens to the left of and
above the shutter. The metering field
(diameter: 12 mm, i.e. approx. 13% of the
negatives size) is situated in the centre of the
first shutter curtain.
The unevenness of the white is not a result of
poor manufacturing tolerances, but is due to
the fact that a thick, complete coating cannot
be applied to the rubberised cloth shutter
curtain without the shutter performance being
impaired. The irregular structure of the
metering spot in no way affects the meter
reading.
The lens f-stop and shutter speed for correct
exposure are indicated by the appearance of
the light balance ( ) in the viewfinder: the
exposure is correct when only the round LED
in the middle comes on.
Switching on the exposure meter
The exposure meter is switched on by light
pressure on the shutter release button (7),
providing that the shutter is cocked and the
shutter speed dial is not set to "B" or "OFF".
When one of the two triangular LEDs or the
central round LED comes on, the exposure
meter is ready for operation.
