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 580EX or 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 
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 the 
580EX, 550EX, or 420EX as a slave) are possible to 
achieve various macro flash effects.
