External Speedlites - Canon EOS 4000D Instruction Manual

External Speedlites

EOS-dedicated, EX-series Speedlites
Easy basic operation, like using a built-in flash.
When an EX-series Speedlite (sold separately) is attached to the
camera, almost all the autoflash control is done by the camera. In other
words, it is like a high-output flash attached externally in place of the
built-in flash.
For detailed instructions, refer to the EX-series Speedlite's
instruction manual. This camera is a Type-A camera.
Canon Speedlites other than the EX-series will not fire.

If the camera is used with a flash unit or flash accessory dedicated to

another camera brand, not only will the camera not operate as usual but
it may also result in a malfunction.
The flash fires only once even when MULTI flash is set with the

Speedlite.
When using an external Speedlite, attach it after retracting the built-in

flash.
With an EX-series Speedlite not compatible with flash function settings

(p.197), only [Flash exp. comp] and [E-TTL II meter.] can be set for
[External flash func. setting]. ([Shutter sync.] can also be set with
certain EX-series Speedlites.)
If flash exposure compensation is set with the external Speedlite, the

flash exposure compensation icon displayed on the camera's LCD
monitor will change from y to 0.
If the external Speedlite's Custom Function has the flash metering mode

set to TTL autoflash, the flash will not fire.
