Wide-Flash Adapter SW-3 ©
The angle of illumination of the SB-11 by itself is 56°
horizontally and 40° vertically—wide enough for use
with a 35mm wideangle lens. When the Wide-Flash
Adapter is clipped onto the front of the flash head, it in
creases the illumination to 67° horizontally and 48° ver
tically providing just the right amount of coverage when
a 28mm lens is used. With the SW-3 attached, the light
output of the speedlight is reduced resulting in a decrease
in guide number from 36 (ASA/ISO 100 and meters) to
25. The AS7VISO 25 and feet guide number is reduced
from 60 to 42.
