107An EOS-dedicated, EX-series Speedlite (optional) makes flash photographyas easy as normal shooting. You can easily do the flash operations below.For detailed procedures, see the Speedlite’s instruction manual.E-TTL II AutoflashE-TTL II is a new autoflash exposure system incorporating improved flashexposure control and lens focusing distance information, making it more precisethan the previous E-TTL (evaluative flash metering with preflash) system. Thecamera 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) LockPress the camera’s <A> button to lock the flash exposure at the desired partof the subject.• Flash Exposure CompensationIn the same way as normal exposure compensation, you can set exposurecompensation for flash. With a Speedlite, the flash exposure compensation canbe 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 withFEB-compatible Speedlites). Set flash exposure bracketing up to ±3 stops in 1/3-stop increments.During FEB shooting, the <d> icon will blink in the viewfinder.• E-TTL II Wireless Autoflash with Multiple SpeedlitesAs with wired, multiple Speedlites, wireless E-TTL II autoflash with multiple Speedlitesprovides all the above features. Since connection cords are unnecessary, flexible andsophisticated lighting setups are possible (only with wireless-compatible Speedlites).The flash cannot be fired with an EZ/E/EG/ML/TL-series Speedliteset in the TTL or A-TTL autoflash mode. Use the Speedlite’s manualflash mode instead if provided.Using EOS-Dedicated, External SpeedlitesWith EX-series SpeedlitesAbout EZ/E/EG/ML/TL-series Speedlites
