Frame Counter
The frame counter located on
top
of the camera works
automatically to show how many frames have
been
exposed. The numbers 20 and 36 are colored red to
correspond to the number of frames in a standard
3Smm cartridge. The frame counter stops just past
the 36-frame mark and
resets
itself automatically to
"S", two frames
before
"0", when the camera
back
is
opened for reloading.
Film Speed
(ASA)
Setting
Some
films are more sensitive to ligh t than others. A
fUm's sensitivity is commonly
known
as its
"spee
d,"
expressed in
ASA numbers.
In
order to work with films of
different
speeds, the
Nikkormat
FT3's
light-meter circuit must be adjusted
for the
ASA
number of
the
film used, This is done
by
means
of a slotted index
pointer
located on the
bottom
of
the
shutter-speed ring.
The ASA
film-speed
scale
has numbered
settings
for
speeds from
ASA
12-
1600
with
dots
between
each
pair
of numbers for
intermediate settings such as ASA 64, 80, etc.
.
Pull up the ASA
lock
on
top of the
shutter-speed
lever
and,
while holding the lock up,
slide
the
slotted
ASA index pointer until it lines up with the ASA
number
of
the
film
in use
.
After
releasing
the ASA
lock, check that the ASA index pointer is
securely
locked into position.
