Auto Aperture Flash Mode
The SB-5000’s light sensor for non-TTL auto flash measures the flash that
is reflected on the subject, and the SB-5000 controls the flash output level
according to the lens and camera information transmitted to the SB-5000,
including ISO sensitivity, exposure compensation value and aperture.
• When no aperture information is transmitted to the SB-5000, the flash
mode is automatically set to non-TTL auto flash.

The SB-5000 emits monitor pre-flashes before actual firing to obtain
reflected flash data.
