Compact flash for on-camera use

The Canon Speedlite 430EX III-RT fits directly onto a hot shoe and draws power from four AA batteries. Its zoom head covers 24-105mm and delivers a guide number of 43m at ISO 100. The built-in catch-light panel helps lift facial highlights for portrait work. A dot-matrix LCD and multi-dial provide direct access to settings.

Slide onto hot shoe and set zoom

Installation is a simple slide-and-lock onto the camera hot shoe; the flash head zooms automatically or manually to match the lens focal length. Recycling time ranges from 0.1 to 3.7 seconds with alkaline cells and 0.1 to 2 seconds with Ni-MH cells, so carry fresh batteries for consistent bursts. The LCD can be dim in bright sun, making menu changes slower outdoors.

Check hot shoe compatibility and battery type

Verify that your camera body has a standard ISO hot shoe with full electronic communication for TTL metering. Decide whether you will use alkaline or Ni-MH AA cells, as recycle speed differs markedly between the two. The unit was first listed by the manufacturer on 26 January 2022, so firmware updates from that period may apply.
