WITH NIKON
F4
OR
F·801/N8008-----
The
58-24 takes full advantage of the
F4
and
F-801/NSOOS's
built-in
computer, which automatically synchronizes the
camera's shutter speed and lens aperture to provide precisely
controlled exposures. The capability to handle wider brightness
ranges
and use fill-flash under more complex conditions varies
from
automatic operation to more advanced user-controlled
options.
With
the Nikon
F4
or
F-801/NSOOS,
by setting the
58
-24 to TTL
auto
flash mode, you will achieve advanced yet simplified fill-
flash
photography.
You
can choose any of the following flash
categories-Matrix
Balanced Fill-Flash, Center-Weighted Fill-Flash or standard TTL
flash,
according to the 58-24's TTL mode (with or without auto-
matic flash output level compensation) and camera's metering
system
(Matrix or Center-Weighted).
