ISO sensitivity (SB-800/SB-600)
When used with optional SB-800 and SB-600
Speedlights, i-TTL flash control can adjust for ISO
sensitivities between 100 and 1600. It may not be able to
adjust flash level appropriately for values over 1600.
When [ON] is set for the [ISO AUTO CONTROL] under
[ISO AUTO CONTROL] under [S EXPOSURE] in the
[SET UP] menu (➝p.154), ISO sensitivity will
automatically be adjusted as required for optimal flash
output. This may result in foreground subjects being
underexposed in flash photographs taken at slow shutter
speeds, in daylight, or against a bright background. In
these cases, choose a flash mode other than slow sync or
select mode or and choose a larger aperture.

allows SB-series Speedlights, including the SB-800, 600,
80DX, 50DX, 28DX, 28, 27, 23, 22S, and 29S to be
mounted directly on the camera without a sync cable. The
accessory shoe is equipped with a safety lock for
