Using EOS-Dedicated, External Speedlites With EX-series Speedlites An EOS-dedicated, EX-series Speedlite (optional) makes flash photography as easy as normal shooting. You can easily do the flash operations below. For detailed procedures, see the Speedlite's instruction manual. E-TTL II Autoflash E-TTL II is a new autoflash exposure system incorporating improved flash exposure control and lens focusing distance information, making it more precise than the previous E-TTL (evaluative flash metering with preflash) system. The camera can execute E-TTL II autoflash with any EX-series Speedlite. • High-Speed Sync (FP flash) With high-speed sync, you can set a sync speed faster than 1/250 sec. • FE (Flash Exposure) Lock Press the camera's button to lock the flash exposure at the desired part of the subject. • Flash Exposure Compensation In the same way as normal exposure compensation, you can set exposure compensation for flash. With a Speedlite, the flash exposure compensation can be set up to ±3 stops in 1/3-stop increments. • FEB (Flash Exposure Bracketing) The flash output is changed automatically for three successive shots (only with FEB-compatible Speedlites). Set flash exposure bracketing up to ±3 stops in 1/ 3-stop increments. During FEB shooting, the icon will blink in the viewfinder. • E-TTL II Wireless Autoflash with Multiple Speedlites As with wired, multiple Speedlites, wireless E-TTL II autoflash with multiple Speedlites provides all the above features. Since connection cords are unnecessary, flexible and sophisticated lighting setups are possible (only with wireless-compatible Speedlites). About EZ/E/EG/ML/TL-series Speedlites The flash cannot be fired with an EZ/E/EG/ML/TL-series Speedlite set in the TTL or A-TTL autoflash mode. Use the Speedlite's manual flash mode instead if provided. 107
