Canon’s powerful Speedlite brings all the features and performance of the previous-generation Speedlite EL-5, and adds even more robust wireless, off-camera capabilities — extending its potential range from the transmitter or sender flash unit to 164 feet (nearly 50m).  Flash performance is excellent, beginning with its flash coverage and power.  Automatic or manual zooming of the flash head can match the coverage of 24mm to 200mm or longer lenses, on a full-frame camera (equivalent to 15mm–125mm+ lenses on an APS-C sensor camera).  Maximum flash power delivers a Guide Number of approximately 169.9 (in feet) or 60 (in meters), zoomed to the 200mm position.  That translates into an effective flash distance range, at its 35mm zoom setting, of up to 42 feet, at f/2.8 and ISO 100 — that doubles to approximately 84 feet at ISO 400.

The good news doesn’t end there.  A powerful Canon LP-EL rechargeable battery pack delivers up to 350 flashes at full manual power — and many more at reduced power settings — along with 1.2 second flash recycling (again, at full manual power).  There’s a built-in, continuous LED modeling lamp, to preview lighting coverage and shadows.  And it’s fully integrated into Canon’s Wireless E-TTL flash system, compatible with all previous radio-based Canon wireless flash units and transmitters.  Likewise, it’s fully compatible with Canon EOS cameras equipped with the advanced Multi-function Shoe design, permitting extensive integrated control between camera and Speedlite.  And for those who prefer to use the controls on the flash, the EL-5 (Ver. 2) retains the superb control dial, joystick, and LCD screen from the original EL-5.

IMPORTANT  Speedlite EL-5 (Ver. 2) can only be shoe-mounted to Canon EOS mirrorless cameras with Canon’s Multi-function Shoe design.  It cannot be attached to any EOS Digital SLR cameras, or to EOS R-series cameras using the original, 5-pin hot shoe connector design.
