Technical Notes/Appendix 117
Flash Control ( 99–101)
The following types of flash control are supported when a CPU lens is used in combination
with the built-in flash or optional SB-400, SB-800, or SB-600 Speedlights.
•
i-TTL Balanced Fill-Flash for Digital SLR
: Flash output is adjusted for a natural balance between
the main subject and the background.
•
Standard i-TTL Fill-Flash for Digital SLR
: Flash output is adjusted for the main subject; the
brightness of the background is not taken into account. Recommended for use with
exposure compensation, for shots in which the main subject is emphasized at the
expense of background details, or when using an SC-series 17, 28, or 29 sync cable.
Standard i-TTL flash control is used with spot metering or when selected with the optional
Speedlight. i-TTL balanced fill-flash for digital SLR is used in all other cases.
Shutter Speeds Available with the Built-in Flash
The following shutter speeds are available when the built-in flash is used.
Aperture, Sensitivity, and Flash Range
Flash range varies with sensitivity (ISO equivalency) and aperture.
