Shoe-mount Speedlites
An EX-series Speedlite can be attached to the camera's
hot shoe. In the same way as normal exposures, you can
use E-TTL II autoflash for flash exposures.
Macro Lites
The EX-series Macro Lites (two models) are ideal for
close-up flash photography. You can fire only one or both
flash tubes and control the flash ratio to easily obtain
sophisticated lighting effects with E-TTL II autoflash.
