Engineered for fast frame-rate shooting, the Canon Speedlite 600EX II-RT improves on the older 600EX model with faster continuous firing and up to 50% more flashes during high framerate shooting. Use it off-camera or in the hotshoe, the 600EX II-RT is extremely versatile and offers wireless shooting via radio and optical transmission, and performs in the most demanding situations, making it an ideal companion for the EOS-1D X Mark II. The unit features a 60 (m, ISO 100) guide number and recycles silently in as little as 3.3 sec, and the optional CP-E4N battery pack shortens this time even further.
