Canon 220EX - Manual (Page 21)

FP Flash
When used with Type A cam­
eras, FP (Focal Plane) flash, or
high-speed sync, enabies the
Speedlite 220EX to synchronize
with a shutter speed that is
faster than the camera maxi­
mum sync speed when the FP
flash indicator is lit. When a
sync speed faster than the cam­
era maximum sync speed is set,
the Speedlite 220EX is set to
the high-speed sync mode auto-
maticaliy and 4
h
is displayed in
the viewfinder.
■ FP flash can be used in the P,
Tv, Av, M, and DEP modes.
■ FP flash is effective when you
want to use fill flash for an
outdoor portrait while blurring
the background with a large
aperture setting. It can also
be used to produce a catch-
light in the subject's eyes, or
to simply eliminate harsh
shadows. The result is most
pleasing when a fast (large
aperture) lens is used.
Taken with FP flash at 1/2000 sec ,
f/2.0 (EF 100mm f/2.0 lens)
Taken with normal flash at 1/125 sec.,
f/9.5 (EF 100mm f/2.0 lens).
1^ • Use of FP flash is not applicable for flash photography with fully-auto-
L-|l matic flash operations.
• Set the camera to Av or M mode when taking pictures with a large
aperture setting.
• FP flash is canceled automatically when the camera is set to the fully-
automatic flash operation, or when the power of the Speedlite 220EX is
turned off.
When using fill flash in the Av mode, it is recommended that the FP
■ ' flash be used so that there is no limitation in using a faster shutter
speed than the camera maximum sync speed.
