Nikon Camera F3AF - Manual (Page 111)

for ASA/ISO 100 in Section B, and go down diagonally until the
protruding line intersects with Section C's vertical line for a
shutter speed of 1/2000 sec. (the FSAF’s fastest shutter speed)
this time. Then follow the horizontal line that leads to Section
D’s EV value for ASA/ISO 100, and you will get a reading of EV
16. This means that at an f/stop of f/5.6 at ASA/ISO 100 and at
shutter speeds from 8 to 1/2000 sec., the effective metering
range is EV 2 to 16, which is well within the F3AF's metering
range of EV 1 to EV 18.
The green area in Chart 1 encompassed by the heavy lines in
Section C demonstrates the usable shutter speed range to
match any film speed/aperture combination at ASA/ISO 100.
(The minimum aperture of the lens is f/16.)
Similarly In Chart 2, the usable range (at ASA/ISO 100) for the
AF-NIkkor 80mm f/2.8 lens Is shown In green.
Two red lines in Section C of both charts indicate the EV value
ranges of the scene brightness usable with autofocus or focus-
aid operation. Therefore, the combinations of shutter speeds
and apertures Indicated in the areas outside the lines are not
usable.
