Set T He Zoom Setting Knob - Nikon Speedlight SB-16 Instruction Manual

2) Set the zoom setting knob
Turn the zoom setting knob at the center on the dial until
the zoom setting index is opposite the same letter as you
selected in setting the zoom head. For example , if you
set the zoom head at T for a 85mm lens, the zoom set-
ting knob must also be set at T.
Note: The
W,
setting on the dial is used when the wide-flash adapter is
attached to the flash unit with the zoom head set at WI.
3) Determine the exposure
Depending on which shooting mode you 've selected,
read off the usable f/stop(s) from the dial. In either the
TTL or non-TTL automatic mode, more than one f/stop is
usable. When choosing an aperture , make sure that your
subject is within the auto shooting range indicated by the
color-coded lines. The larger the aperture (the smaller
the f-number) you select , the greater the maximum
shooting distance, whereas the smaller the aperture (the
larger the f-number), the less the maximum shooting
distance. If the subject distance remains the same , the
larger the aperture you select, the less depth of field in
the final photograph; however, the recycling time is
shorter. On the other hand , the smaller the aperture , the
greater the depth of field , but the recyc ling time is longer.
Therefore , in choosing an flstop , all these factors should
be taken into consideration .
