• These flash units feature a built-in infrared spotbeam
to assist the autofocus system in dim light and low-
contrast conditions.
• The auto zoom function will automatically adjust the
angle of discharge according to the lens focal length
only when an F or FA lens is in use.
• The AF500FTZ features a wireless slave-sync flash
function.
• The flash effective range appears on the LCD panel
only when an A, F, or FA lens is in use.
• Multiple flash burst on a single frame is possible with
the AF500FTZ.
• These flash units feature the contrast-control-sync
flash. See page 79 for more details.
• In the Programmed AE, Shutter-Priority AE, or
Aperture-Priority AE, the TTL Auto Flash Mode will
be set automatically even if the flash is set to Manual.
• When the flash is charged and left unused for about
3 minutes, the power automatically switches off to
save battery power. Depressing the shutter release
button halfway down will restart charging of the flash
units.
AF24-0FT, AF400FTZ

Aperture-Priority AE: TTL Auto Flash Mode will be
set automatically even if the flash unit is set to

AF200T, AF220T, AF280T. and AF400T
• If the TTL auto mode is selected, these flash units can
be used for daylight-sync shooting, because the shut­
ter speed is adjusted according to the ambient bright­
ness. The slower shutter speed varies according to
the lens focal length. The shutter speed varies within
the shutter speed range of 1/100 of second to a
slower speed which does not cause camera shake.
However, when a non-autofocus lens is in use, the
shutter speed is set to 1/100 of second. The aper­
ture value will also be fixed but will vary depending on
what ISO film is loaded.
