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.
Thanks to a wide lens coverage, from 20mm to 200mm, or to 14mm via the built-in adapter, photographers can 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.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 Speedlites can be used together off-camera for dramatic multi-flash photography – great when shooting interiors.
To ensure consistent color in both the foreground and background of an image, the Speedlite 600EX II-RT features a new color filter holder. By placing a color filter over the front of the flash head, the color temperature of the flash can be made to match that of the ambient light. Color information and light output decrease can be transmitted from the Speedlite 600EX II-RT to the camera for proper white balance and exposure.
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.
