Flash Photography
The built-in flash or an EOS-
dedicated, EX-series Speedlite
enables E-TTL II autoflash
(evaluative flash metering with
preflash), making flash
photography as easy as normal
shooting. The result is natural-
looking flash photos. In the Basic
Zone modes (except <3> <5>
<7>), flash photography is fully
automatic. In Creative Zone modes,
flash can be used whenever
necessary.
