Wide-Flash Adapter SW -5
CD
The angle of illumination of the SB-14 by itself covers the
picture angle of a 28mm wideangle lens. When the wide-
flash adapter
is
attached onto the front of the flash head,
it
increases
the illumination from 67° to 77° horizontally
and 48° to 56° vertically, providing just the right amount
of coverage when a 24mm lens is used.
