E-TTL II Flash metering
Portable and compact, the Speedlite 430EX II is high powered with a Guide Number of 43 suitable for both bounce flash and telephoto lens shooting. E-TTL II metering with compatible cameras gives accurate flash exposure in all situations, even when bouncing light from a wall or ceiling.
For more control the flash power can be set manually in 1/3rd stop increments from 1/1 to 1/64th power.

24-105mm auto zoom head
Used with a compatible EOS digital SLR, the Speedlite 430EX II automatically detects the camera’s sensor size and zooms the flash head for optimum scene coverage. This reduces wasted light and improves both battery life and recycling times.
The 24-105mm auto zoom head and a 14mm wide-panel diffuser provides flash coverage for a wide range of shooting situations.
The swivel and tilt head allow the use of bounce flash to create softer lighting when using a single flash on-camera.

Wireless Slave
The Speedlite 430EX II can be used as a wireless slave flash unit triggered by an appropriate master flash unit. The small size and high power output make it an ideal slave flash for creating a portable studio with multiple flashguns.

Power source
Powered by 4 x AA batteries the Speedlite 430EX II is lightweight, portable and compact enough to keep with you. Recycling is approximately 20% faster than the previous model and nearly silent to avoid scaring timid wildlife subjects.

Durability
A metal mounting foot and quick release latch ensure the connection between the camera and Speedlite is both easy to use and secure.

Flash control
When used with a compatible camera all aspects of flash control, including flash power settings and all nine custom functions can be adjusted from the camera menu**.

AF Assist
Covering 1-9 AF points, the Speedlite 430EX II can emit an infra-red focusing beam providing contrast for the lens to focus on when shooting in low light conditions.
