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 metering system to adjust flash output for natural balance between
main subject and ambient background lighting. If type G 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 0 149). Not available when spot metering is used.
• Standard i-TTL 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 flash for digital SLR is activated automatically when
spot metering is selected.
The flash control mode for the built-in flash can be selected using Custom Setting e3 (Flash
cntrl for built-in flash, 0 246). The information display shows the flash control mode for
the built-in flash as follows:
