The Speedlite 600EX-RT is a high-performance TTL flash unit designed to meet the expanding creative needs of modern professionals. Integrated radio frequency triggering, in addition to standard infra-red wireless flash control, allows photographers to achieve exciting results with complex on-and-off-camera lighting set- ups. Using one master 600EX-RT or the new ST-E3-RT radio-frequency wireless Speedlite transmitter, up to 15x 600EX-RT flash units, positioned up to 30m away, can be remotely triggered – offering great potential to experiment with more creative lighting techniques and effects. EOS cameras with a connected Speedlite 600EX-RT can also be triggered remotely by either model, allowing photographers to explore more extreme shooting angles to produce surprising and inspiring creative results.
