EXPOSURE
MEASUREMENT
The Nikkormat FT2
features a center-weighted thru-
the-lens exposure metering system cross-coupled to
the shutter speed and aperture controls. The meter
reads the light over the entire focusing screen but
favors
a central
area.
This
means
that correct
ex-
posures
are
possible
even in situations where an
averaged reading would result in wrong exposure—
with strong backlighting, for example.
Full-Aperture Exposure Measurement
The
FT2
meter
takes advantage
of automatic
dia-
phragm feature of Nikkor Auto Lenses to measure
light at the maximum aperture of the lens. This insures
a bright viewfinder image for viewing and focusing and
minimizes
the influence
of light entering through
the finder eyepiece.
In order for the FT2 meter to measure exposure at
full aperture with lenses of different maximum aper-
ture, it must be coupled with the maximum aperture
of the lens in use. This is done each time the lens is
attached or changed by turning the aperture ring of
the lens through its entire range (see ''Changing the
Lens," p.22.).
Turning On the Meter
To switch on the Nikkormat FT2'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.
