Flash Photography
With EX-series Speedlites
An EOS-dedicated, EX-series Speedlite makes flash photography as easy as any AE mode. For details on using the EX-series Speedlite, refer to the Speedlite’s instruction manual. The EOS-1Ds Mark II is a Type-A camera compatible with all EX-series Speedlites providing the features below.
• 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)
High-speed sync (FP or focal-plane flash) enables flash synchronization with all shutter speeds from 30 sec. to 1/8000 sec.
• FE (Flash Exposure) Lock
Press the camera’s <I> button to lock the flash exposure at the desired part of the subject. This is the flash equivalent of AE lock.
• Flash exposure compensation
In the same way as normal exposure compensation, you can set exposure compensation for flash. Set flash exposure compensation up to ±3 stops in 1/3-stop increments.
• FEB (Flash Exposure Bracketing)
FEB is the flash version of AEB. (Only with FEB-compatible Speedlites.) Set flash exposure bracketing up to ±3 stops in 1/3-stop increments.
• E-TTL II wireless autoflash with multiple Speedlites
Like with wired, multiple Speedlites, E-TTL II wireless 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.)
