Canon EOS 1DS MARK II 9443A009 Instruction Manual (en)

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 <
> 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 
• 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.)
