Canon today announces the latest addition to its EX Speedlite flash unit range, the Speedlite 430EX II. A high-powered compact flash, the Speedlite 430EX II has a guide number of 43 (m/ISO 100 at 105mm) and a built-in wide panel to allow coverage suitable for wide angle lenses to 14mm.

The Speedlite 430EX II offers fast, silent recycling and full control via the menu system of compatible EOS cameras. It is ideal for both amateurs and professionals seeking a versatile, all-purpose flash.

New features
For maximum flexibility and ease of use, the Speedlite 430EX II incorporates a number of new features. Recycle times have been reduced by approximately 20%, with the recycle process performed silently to minimize distraction. A new metal mounting foot with redesigned connection pins provides ultra-stable communication between the camera and flash; for rapid connection to the camera, a new quick release and locking mechanism is also incorporated.

Used in Manual mode, the Speedlite 430EX II offers settings in 1/3 stop increments for increased precision of operation. Plus when used with compatible EOS cameras every setting on the Speedlite 430EX II can be controlled via the camera menu system, allowing rapid, intuitive alteration of settings.

System flash
The Speedlite 430EX II is a key component of the integrated flash system for both analogue and digital cameras, and is fully compatible with the distance-linked E-TTL II system found on recent EOS cameras. It can also be used as a slave unit when combined with a master unit in a wireless flash setup.

White balance compensation
Slight variations in a flash gun's voltage and brightness can destabilize white balance in respective frames during continuous shooting. The Speedlite 430EX II compensates for this by transmitting color information from the flash to the camera. This information is then used to optimize the white balance setting for each individual image. This function works with the camera set to Auto WB or Flash Mode.

Matching sensor size
When mounted to compatible EOS digital cameras, the Speedlite 430EX II detects whether the sensor is full frame, APS-C or APS-H. The flash's zoom position is then automatically adjusted, optimizing flash coverage and the amount of charge needed per shot. 

Fully featured for full control
Other features on the Speedlite 430EX II include 1st and 2nd curtain flash synchronization, exposure compensation, and an expanded range of nine custom functions.
