Canon Speedlite 550EX Instructions

Short Description
The Canon Speedlite 550EX is a powerful, high-output flash unit featuring E-TTL (Evaluative-Through-The-Lens) autoflash control. It can be used as an oncamera Speedlite or as a master or slave unit in a wireless, multi-Speedlite system. When used with Type-A cameras (listed below), the 550EX obtains natural-looking flash pictures by balancing the flash output and existing light. The 550EX also enables high-speed sync (FP or Focal-Plane flash), FE (Flash Exposure) lock, FEB (Flash Exposure Bracketing), bounce flash and area AF-assist. When used with Type-B cameras (listed below), the 550EX works as a TTL autoflash unit. With Type-B cameras, some 550EX features are not available. Refer to the tables below to check your camera type and the features available. This Instructions booklet has separate sections for Type-A and Type-B cameras. Read the section which applies to your camera.
