Shooting Dark Subjects
In all exposure modes, with a subject darker than EV10 at ISO
100, the ready-light LED blinks.
Programmed TTL auto flash photography in program and
shutter-priority auto exposure modes
In programmed TTL auto flash photography, the N4004S auto­
matically adjusts the shutter speed to 1/100 sec*, and selects
the appropriate aperture according to the speed of the film in
use (ISO).
* If shutter speed is set to B, or to 1/60 sec. or slower in shutter-priority
exposure mode, shutter fires at the speed set, and correct aperture is
selected accordingly.
The usable ranges for film speed, aperture and shooting dis­
tance in programmed TTL mode are as follows.
ISO 25 50 100 200 400
Aperture 1.4 2 2.8 4 5.6
Shooting Range Approx. 1.4-4.2 m
‘Ready-light blinks when using film with ISO speed over 400.
•When using a lens with a slower maximum aperture (larger
F-number) than the numbers listed above, the aperture will be
automatically set to the lens' maximum aperture, thus shortening
the shooting range, (i.e., if maximum aperture is f/3.5 and film speed
is ISO
too,
aperture is set to 3.5 instead of f/2.8). For longer flash
shooting distances (up to 4.2 m), use film with a speed of ISO 400.
TTL auto flash photography in aperture-priority auto and
manual exposure modes
In aperture-priority auto mode,
the N4004s automatically
adjusts the shutter speed to 1/100 sec. In manual mode, when
