The Speedlite 430EX improves on many specifications of its predecessor and includes new features to maximize digital image quality when using a flash. These include the automatic selection of camera white-balance settings and auto-adjustment of the zoom flash position to match the sensor size of the camera to which the unit is attached. The Speedlite 430EX has increased its guide number to 43 (m/ISO 100 at 105mm) and has approximately 40% faster recycling time than the Speedlite 420EX.

An ultra-bright, two-LED configuration focus assist beam has been designed to be compatible with all focus points within the frame of all EOS AF systems, up to 9-point AF.

Optimum flash coverage
The flash head zoom covers the range of 24mm to 105mm and an integrated diffusion panel allows extended wide-angle coverage to 14mm. When attached to digital EOS cameras with smaller than full-frame sensors (such as the EOS-1D Mark II N and EOS 20D) the Speedlite 430EX gives a more accurate flash coverage by detecting the model to which it is attached and automatically narrowing the angle of coverage. This has the effect of eliminating light loss in peripheral areas and extending the effective flash range.

Ideal white balance
The Speedlite 430EX automatically transfers color temperature information to recent models of digital SLR cameras. The camera then sets the white balance optimally for the flash shot. This feature works when the camera's white balance mode is set to Auto White Balance (AWB) or Flash white balance mode.

E-TTL II
The Speedlite 430EX is fully compatible with the distance-linked E-TTL II system found on recent EOS cameras and supports other EOS cameras that do not support E-TTL II, when required. For a complete multiple flash system, the Speedlite 430EX serves as a wireless slave when either the Speedlite 580EX, Macro Ring Lite MR-14EX, Macro Twin Lite MT-24EX, or Speedlite Transmitter ST-E2 is used as a master.

Upgrade for control
An intuitive and ergonomic interface includes an LCD panel for a clear indication of modes and settings. A single bounce lock release button provides immediate control over the bounce head angle for flexible positioning of the flash head. The flash head can be moved up from 0 to 90 degrees (5 settings), left from 0 to 180 degrees (7 settings), and right from 0 to 90 degrees (4 settings). Six custom functions allow customization of the flash operations. Despite high power and short recycling times, the unit is small and lightweight.

Fully synchronized
Features include 1st and 2nd curtain flash synchronization, plus manual adjustment of flash output from full to 1/64 power (7 levels).

• Significantly greater user control via new LCD panel on the rear of the flash
• The Wide-angle pull-down panel covers a 14mm lens (on a full-frame camera)
• Slightly higher max. guide number at 105mm setting (GN 141 feet, at ISO 100)
• Auto conversion of flash zoom coverage with compatible digital SLRs
• White balance info communicated instantly to compatible digital SLRs
• Bounce upward to 90°; swivel right (to 90°) and left (to 180°)
• 14% lighter and approx. 25% smaller in overall volume than top-of-the-line 580EX
• Six flash custom functions are built into the 430EX (set on the rear LCD panel)
