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

Nikkor(No. 250525 or smaller)
58mm

or
smaller)

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.
