Why use an external flash? Take a new approach to lighting with a Speedlite flash that’s powerful, versatile and portable. Radio-frequency triggering makes off-camera flash easy to do, and opens up new ways to get creative with your photography. 

  • Powerful, yet compact enough to take anywhere
  • Simple controls and an intuitive interface
  • Use remote flash to create the look you want
  • Shoot flattering portraits using bounced light
  • Integrates with other Speedlites as part of the EOS Family

In addition to the newly implemented radio system for wireless flash, optical slave transmission is still available for greater functionality. The 430EX III-RT's electronics have been sped up with a faster recycle time of 0.1 to 3.5 seconds along with a Quick mode that shortens this to just 2.5 seconds. Also, it offers enhanced Flash Exposure Compensation and Light Distribution settings for making very specific adjustments to the output settings.

Versatility is still key with this compact unit, offering high-speed, 1st and 2nd curtain sync modes along with a variety of custom functions for setting the Speedlite up exactly as you need. A color filter and bounce adapter are included as well for adjusting the color temperature and brightness of the flash for more balanced lighting. And, it runs on 4 AA batteries.
