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 autoflash, high-speed sync (FP flash), and FE lock. With the 550EX, an easy-to- use, wireless E-TTL autoflash system is possible with multiple Speedlites.
Macro Ring Lites
The EX-series Macro Ring Lites are ideal for macro 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 autoflash. Also, high-speed sync (FP flash), FE lock, and a multi-Speedlite, wireless system (with 550EX as a slave) are possible to achieve various macro flash effects.
