The Speedlite 600EX II-RT delivers uncompromised performance, making it the perfect companion for the flagship EOS-1D X Mark II. Firing up to 50 per cent more flashes continuously compared with its predecessor, and a 100 per cent increase when used with the new CP-E4N, it ensures you capture even more of the action. The new and improved heat measure technology prevents overheating and allows longer bursts of flashes.
A guide number of 60m at ISO 100 allows you to creatively light your subject over a wide range of distances and large areas, ideal for capturing the whole congregation at a wedding. Thanks to a wide lens coverage, from 20mm to 200mm, or to 14mm via the built-in adapter, photographers can easily control how light is spread across a subject.

For creative illumination, the flash features a wireless slave function, enabling photographers to make the most of off-camera lighting. The radio control function, pioneered by Canon, provides further creative freedom, allowing photographers to build mood and atmosphere into a scene at up to 30m away by simulating multi-directional light. Up to 15 Speedlites² can be used together off-camera for dramatic multi-flash photography – great when shooting interiors.
For portraiture specialists, the new and included bounce adapter SBA-E3 provides more freedom to bounce light from walls and ceilings for a softer, more natural result, whilst the rotating bounce flash eliminates unwanted shadows. The new clip-on hard coloured filters further helps when balancing flash with ambient light.
