Select and set aperture.
' The aperture scale window shows usable apertures. (Depending on
film speed in use, all usable apertures may not be shown in the aperture
scale window; for usable apertures, see table on next page.)
For example, with the film speed index at ISO 100, you can select any
aperture from f/2 to f/22. With the zoom set ring at N, selecting f/4 lets you
take pictures of subjects 1m to 7.5m (approx. 3.3ft. to 25ft.) away.
With Nikon F-401/N4004, use camera’s aperture dial.
Next, turn on flash unit and take
shot in the same manner shown in
“BASIC OPERATION,” steps 12 to
15.
