Programmed exposure measurement graph
The
graph represents the optimum combinations of
f/stop and shutter speed, for the brightness of any
scene, which were determined through intensive
statistical and empirical studies and fed into the FG's
computer brain for its pre-arranged exposure pro-
gram.
Thus, when actual exposure measurement
takes place at the time of shooting, the ideal combi-
nation for actual conditions
is
selected and perfect
exposure results for every shot.
(Graph-green
line represents the curve for the f/1.4
lens.
For lenses with other apertures, the graph
is
read from that particular aperture opening until inter-
section with the diagonal line and then
in
the same
downward
line, e.g., the black line for the f/4 lens.)
Notes:
1)
On
P.
the following lenses will cause slower shutter speeds
than those indicated
in
the viewfinder while
correct
expo-
sure
is
assured. Therefore,
in
cases where more
exact
shutter speed information
is
desired, A
or
manual mode
is
recommended:
50mm

2)
On
p,
the following lenses and accessories cannot be used
as they do not have an aperture coupling device. Use
these lenses on A
or
manual modes.
All Reflex Nikkors
All
PC
Nikkors
(when perspective
is
shifted, use manual mode)
Bellows attachment
Extension Ring
Set K
3)
On
P.
when using teleconverters
or
AI-converted lenses
of
maximum apertures
of
f14.5
or
smaller, shutter speeds
available are limited to very slow ones Therefore, A
or
manual mode
is
recommended.
4)
On
P.
when using AI-converted lenses
of
maximum aper-
ture larger than tl2.8, the metering range for the higher EV
values
will be reduced down to a maximum
of
two
EVs
de-
pending on the aperture.
