Using Eos-Dedicated, External Speedlites - Canon EOS 30D Instruction Manual

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 Speed lite'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
I
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
11
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/MUTL-series Speedlites
The flash cannot be fired with an EZ/E/EG/MLlTL-series Speedlite
set in the TTL or A-TTL autoflash mode.
Use the Speed lite's manual
flash mode instead if provided.
