Guide numbers in the above tables are for when the SB-700 is used with a D3 •
camera with a 1/500 sec. shutter speed.
Guide number with auto FP high-speed sync varies depending on the camera’s •
shutter speed. For example, when the shutter speed is changed from
1/500 sec. to 1/1000 sec., the guide number decreases 1 step. The faster the
shutter speed, the smaller the guide number.
