On-camera flash Canon Speedlite EL-100 allows you to easily increase the brightness of your shots, in both indoor and outdoor environments. This smart flash is more powerful than the built-in ED flash and features an intuitive selection dial that simplifies operation and setup. The Speedlite flash’s vertical and horizontal adjustment capability ensures brighter, brighter results in both indoor and outdoor environments, allowing you to creatively illuminate your subject by reflecting light off walls and ceilings, or by shooting remotely. Explore creative features such as strobe flash, which allows you to freeze a subject with quick shots, and sync mode on the second curtain to emphasize the perception of speed, both perfect for capturing moving subjects. Also, for more three-dimensional lighting effects, use Speedlite EL-100 as a wireless optical transmitter to trigger the flash from different positions or as an optical receiver controlled by compatible EOS cameras.
