Auto aperture flash
The SB-900’s built-in sensor measures the flash illumination reflected from the
subject and controls the flash output in combination with data automatically
transmitted from the camera and lens to the SB-900, including the ISO sensitivity
value, the exposure compensation value, the aperture and focal length of the lens.
Auto aperture flash can be changed to Non-TTL auto flash (kD-8) by using the
custom setting. (kC-22)
The default setting is Auto aperture flash (with monitor pre-flashes).
When no aperture information is transmitted from camera to the SB-900,
flash mode is automatically set to Non-TTL auto flash.
