Built-in Speedlight and Matrix Balanced Fill-Flash
This camera is equipped with built-in Speedlight that provides
an
angle of
coverage for a 28mm lens with a guide number of 15 (IS01 00,
m)
or 49
(IS01 00,
ft.).
Matrix Balanced Fill-Flash ensures proper exposure of the main subject and
background, and controls adequate flash output to create natural-looking flash
photography (with CPU lens).
In
addition to shooting
in
dim light, the flash can be used
in
daylight to reduce
shadows on the main subject or to put catch lights
in
your subject's eyes.
Four flash sync
modes-Normal
Sync, Red-Eye Reduction, Slow Sync and Red-
Eye Reduction with Slow
Sync-are
available with this camera .
• When using a non-CPU lens, standard TTL flash is the only flash mode
available. To ensure optimum performance, use only CPU lenses.
