Non-TTL auto flash mode
Non-TTL auto A flash
The SB-800’s built-in sensor measures the flash illumination reflected from the
subject, automatically controlling the SB-800’s light output to give the correct
exposure. This allows you to make exposure compensation (p. 54) easily by
varying the aperture set on the camera or lens.
No limitation on usable cameras.
Auto Aperture flash (p. 38) is automatically set (default setting) when the SB-800 is used
with cameras compatible with CLS, digital SLRs not compatible with CLS, cameras in
Groups I and II in combination with a CPU lens, and COOLPIX cameras compatible
with i-TTL. To cancel Auto Aperture flash and set to Non-TTL auto flash, use Custom
settings (p. 67).
