Troubleshooting Guide

When I use the <f> mode with flash, the shutter speed becomes slow.

If you shoot night scenes, the shutter speed becomes slow automatically (slow-sync shooting) so that both the subject and background are properly exposed. If you do not want a slow shutter speed to be set, set [8C.Fn I -7: Flash sync. speed in Av mode] to 1 or 2 (p.194).

The flash does not fire.

Make sure the flash (or PC sync cord) is securely attached to the camera.

If you use a non-Canon flash with Live View shooting, set [Silent shoot.] to [Disable] (p.104).

The flash always fires at full output.

If you use a flash unit other than an EX-series Speedlite, the flash will always be fired at full output (p.103).

When the [Flash metering mode] flash Custom Function is set to

[TTL (autoflash)], the flash will always be fired at full output (p.106).

Flash exposure compensation cannot be set.

If flash exposure compensation has already been set with the Speedlite, flash exposure compensation cannot be set with the camera. When the Speedlite’s flash exposure compensation is set to 0, flash exposure compensation can be set with the camera.

High-speed sync cannot be set in the Av mode.

Set [8C.Fn I -7: Flash sync. speed in Av mode] to [0: Auto] (p.194).
