• Guide numbers in the above tables are for when the SB-5000 is used with a D3
camera with a 1/500 second shutter speed.
• Guide number for auto FP high-speed sync varies depending on the camera’s
shutter speed. For example, when the shutter speed is changed from 1/500 second
to 1/1000 second, the guide number decreases 1 step (approx. 1/1.4). The higher
the shutter speed, the smaller the guide number.
