Nikon Nikkormar FT3 - Exposuremeasurement; Full-Aerture Exposure Measurement; Turning on the Meter

EXPOSUREMEASUREMENT
The Nikkormat FT3 features a center-weigh ted,
through-the-lens metering system. The exposure
meter · reads the ligh t intensity over the en tire focus-
ing screen,
but its sensitivity is concentrated on the
12mm diameter spot in the center. This ensures you
of perfect exposures in everyday picture-taking situa-
tions, while still
retaining the selectivity essential for
specialized applications or advanced photographic
techniques.
Full-Aperture Exposure Measurement
When a Nikkor lens fitted with a meter coupling ridge
is
mounted on the camera, the metering system is
cross-coupled
to both the camera 's shutter speed dial
and the lens' aperture diaphragm setting ring. This
allows
you to continue viewing at full aperture while
determining the exposure settings, thus eliminating
finder dim-out and minimizing the influence of stray
light entering the finder eyepiece .

Turning On the Meter
To switch on the Nikkormat FT3's CdS exposure
metering circuit, pull out the film advance lever just
enough - to uncover the red dot on top of the camera
body. When the meter is not in use, press the lever
flush against
the camera body, since the battery is
being drained continuously as long as the lever is in
the "on" position.
