The Speedlite EL-1 is the next generation, all-purpose flash that professionals and advanced amateurs have been seeking, providing durability, reliability and a range of power that opens up a number of possibilities. The new Xenon flash tube offers increased stability for flash output and 14 f-stops of total flash exposure range allowing you to shoot anywhere from a bright 1/1 to a dim, low power 1/8192 to precisely sculpt your scene with light.

The Speedlite EL-1 is designed with the same robust dust and water resistance as our EOS 1D series cameras, has an internal active cooling system for longer and more efficient shooting, simple and accessible controls so it's ready to go when you are, comes bundled with accessories to increase versatility in different lighting situations, and much, much more. It's not just an extension of your camera, it's an extension of your vision.
