Nikon F100 Instruction Manual page 93

• Speedlight SB-27
• Speedlight SB-27 normally uses four AA-type alkaline-manganese batteries
with a guide number of 30/98 (manual flash, 35mm zoom-head position, ISO
100, m/ft., 20°C/68°F).
• Compact and lightweight, the SB-27's flash head rotates from the horizontal
to the vertical position along a 180° arc to control the effect of shadows.
• With the built-in bounce flash adapter, bounce flash operation is possible.
And, with a diffuser card, by bouncing the light off the ceiling or walls, you
can soften the shadows and produce more natural portraits or close-up
photographs. Bounce flash can also make your subject's eyes appear more
vibrant.
• 3D Multi-Sensor Balanced Fill-Flash, Standard TTL Flash, manual flash
output level compensation, non-TTL auto flash and manual flash are
compatible with the SB-27.
• The SB-27's AF-Assist Illuminator enables autofocus operation in a dark
environment.
• Wireless Slave Flash Controller SU-4
• TTL multi-flash, where a Speedlight to which Wireless Slave Flash Controller
SU-4 is attached is fired simultaneously with the Speedlight attached to the
F100, can also be used.
