Shoe-mount Speedlites
Flash photography with an EX-series Speedlite is as easy
as normal auto exposure shooting without flash. All EX-
series Speedlites enable E-TTL II autoflash, high-speed
sync (FP flash), and FE lock. With the 550EX, an easy-to-
use, wireless E-TTL II autoflash system is possible with
multiple Speedlites.
Macro Ring Lites
The EX-series Macro Lites 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. Also, high-speed sync (FP flash),
FE lock, and a multi-Speedlite, wireless system (with
550EX or 420EX as a slave) are possible to achieve
various macro flash effects.
