AF500FTZ and AF330FTZ • These flash units feature a built-in infrared spotbeam to assist the autofocus system in dim light and lowcontrast 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-synch flash. See page 78 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. AF240FT, AF400FTZ • These flash units feature a built-in infrared spotbeam to assist the autofocus system in dim light and lowcontrast conditions. • In the Programmed AE, Shutter-Priority AE, or Aperture-Priority AE: TTL Auto Flash Mode will be set automatically even if the flash unit is set to Manual. • When the flash unit is charged and left unused for about 5 minutes, the power will automatically switche off to save battery power. Depressing the shutter release button halfway down will restart charging of the flash unit. AF200T, AF280T, and AF400T • If the TTL auto mode is selected, these flash units can be used for daylight-sync shooting, because the shutter speed is adjusted according to the ambient brightness. 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 aperture value will also be fixed but will vary depending on what ISO film is loaded.
