1. Using EOS Dedicated Speedlites
EOS dedicated Speedlites (540EZ, 430EZ, 420EZ, 300EZ, etc.) make
flash photography as simple as pointing and shooting. Moreover, built-in
advanced functions make it easy to achieve professional fill-in flash
effects in outdoor settings as well as automatic control of flash exposure
when shooting at night or indoors. These units feature a built-in AF auxil-
iary light function that assists autofocus in dark situations.
By simply attaching an EOS Speedlite to the camera and turning it on, an
appropriate flash synchronization speed (1/250 sec. or slower) is auto-
matically set on the camera. As soon as the flash is charged, the flash
charge completion indicator appears in the viewfinder. For details, refer to
your speedlite’s instruction book.
● Automatic Flash Output Reduction Control
When using a dedicated speedlite to take a photo of a subject lit by sky-
light-type illumination, the camera automatically reduces the flash unit’s
light output so as not to overexpose the subject.
• The 540EZ's AF auxiliary light is designed to work with all five of the EOS-1 N’s focus
points. Other EZ Speedlites' AF auxiliary light works with only the center focusing point.
• The 480EG does not emit an AF auxiliary light.
• The aperture values displayed on the camera and speedlite LCD panels may some-
times differ. However, the exposure will be correct.
• When using flash in AI Servo AF mode, the flash unit’s AF auxiliary light will not func-
tion. In situations requiring use of the AF auxiliary light, switch to One-shot AF mode.
You can turn off the automatic flash out-
put reduction control function for strongly-
backlit subjects which need extra illumi-
nation from the flash.
