For Manual Operation
Set the ASA/ISO dial and simply read off the f/number
which appears directly above the flash-to-subject dis
tance; then set this aperture on your lens.
For example, with ASA/ISO 100 and a subject 2m (approx.
7 ft.) away, the usable f/stop is f/16 without wide-flash
adapter, or f/11 with the wide-flash adapter attached.
Without referring to the exposure calculator dial, you
can also determine the f/stop by using the following egua-
tion:
f/stop =
guide number
flash-to-subject distance
With ASA/ISO 100 film and meters, the SB-14's guide
number is 32. If the subject is 8m away, divide 32 by 8 to
get f/4.
Caution: For manual operation, be sure to set the shooting mode selector
ol the Sensor Unit SU-2at the "M"position.
