Flash Control Mode

The camera supports the following i-TTL flash control modes:
• i-TTL balanced fill-flash for digital SLR: Flash emits series of nearly invisible

preflashes (monitor preflashes) immediately before main flash.
Preflashes reflected from objects in all areas of frame are picked up by
2016-pixel RGB sensor and are analyzed in combination with range
information from matrix metering system to adjust flash output for
natural balance between main subject and ambient background
lighting. If type G, E, or D lens is used, distance information is
included when calculating flash output. Precision of calculation can
be increased for non-CPU lenses by providing lens data (focal length
and maximum aperture; see page 224). Not available when spot
metering is used.

• Standard i-TTL fill-flash for digital SLR: Flash output adjusted to bring

lighting in frame to standard level; brightness of background is not
taken into account. Recommended for shots in which main subject is
emphasized at expense of background details, or when exposure
compensation is used. Standard i-TTL fill-flash for digital SLR is
activated automatically when spot metering is selected.

Metering

Select matrix or center-weighted metering to activate i-TTL balanced
