Learn to light up your photographic results with a Canon Speedlite Flash.


  • Built-in LED light can be used to illuminate nearby subjects in dim light - especially useful when shooting video, as a modeling light or as an AF assist beam (with Live View), providing up to four hours of continuous lighting with fully-charged AA batteries.

  • Versatile vertical and horizontal bounce capability provides an extended range of possible lighting effects.

  • Flash release function triggers the camera wirelessly from the flash on a 2-second delay, allowing the flash to be repositioned to illuminate the subject.

  • Wireless Slave function supports three groups and four channels, allowing the flash to be positioned off-camera.

  • Flash coverage can be switched by extending or retracting flash head, with Normal (24mm full-frame equivalent, max. Guide No. 79 ft./24m at ISO 100) and Tele (50mm full-frame equivalent, max. Guide No. 105 ft./32m at ISO 100) settings.
