Canon flash / speedlite 430EX: Replacing the popular Speedlite 420EX, the Speedlite 430EX improves on many specifications of its predecessor, and includes new features to maximise digital image quality when using a flash. These include 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 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.
Features advanced 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.
Sophisticated white balance
The Speedlite 430EX automatically transfers colour temperature information to recent models of digital SLR camera. 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.
Flexible flash coverage
The flash head zoom covers the range 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, EOS 40D and EOS 450D) 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.
