Features |
- The fully swiveling bounce head zooms automatically over a range of 24mm-105mm. Its Wireless E-TTL II compatibility permits it to function as a slave unit, triggered by a 580EX, ST-E2, or MR-14EX. Any number of 430EX and 550EX Speedlites can be combined as slave units for creative effects.
- The Speedlite 430EX also automatically transfers color temperature information to recent models of digital SLR cameras. The camera then sets the best white balance setting 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.
- Flash controls can now be set on the flash's rear LCD panel, or directly on the camera's LCD screen on compatible EOS Digital SLR cameras.
- Intuitively placed controls keep features easily accessible, such as adjusting manual flash exposure from full power to 1/64 in 1/3 stop increments, and enabling the second curtain sync function. A separate Custom Function button provides maximum control over various flash functions.
- Nine custom functions are also now available, as well as a flash head that is more maneuverable and capable of more angles for bouncing flash illumination than its predecessor.
- Professional Modes:
- E-TTL II, E-TTL, TTL & Manual
- FP Mode, or high-speed sync, allows the camera to sync with flash at higher shutter speeds
- Wireless TTL flash when combined with ST-E2 Transmitter & multiple 550 EX's
- Automatically adjusts the flash coverage to adjust for differences in chip size on APS-C sized digital cameras
- 20% faster recycling time than the Speedlite 420EX
- Ultra-bright 2-LED focus assist-beam compatible with all focus points of all EOS AF systems, up to 9-point AF
