Speedlite 430EX

Replacing the 420EX, Canon’s 430EX (see 8-7) is a more affordable (by about $100) flash than the 580EX II and is designed as a great companion with many of the mid-range dSLR models — most of which feature an internal flash as well. It is also smaller and lighter than the 580EX II.

If you find that your Rebel XT’s or 40D’s pop-up isn’t enough for every flash situation, the 430EX is a great flash to consider if you want to add an external flash capability.

The 430EX offers manual control over flash compensation and its settings, allowing you to adjust power from 1/64 up to its full capacity in logical increments. You can also use the flash as a slave unit because it has a sensor to detect another flash source. In fact, if you want to set up a master-slave set of flashes, you may want to consider using the 580EX II as the master and the 430EX as a slave.

The flash’s AF-assist beam, which covers up to nine AF points, is effective up to almost 33 feet (10 meters) from its center, and up to 16.4 feet peripherally.

Here are the key features of the Speedlite 430EX:

  • The LCD panel on the rear of the flash offers easy control of six custom fuctions.
  • The wide-angle pull-down panel gives you additional flash coverage for wide-angle shots.
  • The maximum guide number is 43 at a 105mm setting.
  • The flash head can swivel horizontally 90 degrees right and 180 degrees left, and it can tilt 90 degrees vertically.
  • It has auto conversion of flash zoom coverage.
  • The flash range at ISO 100 with 50mm f/1.4 lens is approximately 2.3 to 79.7 feet (0.7 to 24.3 meters).
  • The white-balance information is communicated immediately to the camera.
