A guide number of 60 (metres, ISO 100) allows lighting of a subject over a wide range of distances and large areas, ideal for capturing a large group at a wedding, for example. Thanks to a wide lens coverage, from 20mm to 200mm, or to 14mm via the built-in adapter, you can easily control how light is spread across a subject.
For creative illumination, the flash features a wireless slave function, enabling you 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 (including earlier EX-RT models) 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, while the rotating bounce flash eliminates unwanted shadows. The new clip-on hard coloured filters further helps when balancing flash with ambient light.
The Speedlite 600EX II-RT is available from June 2016 with an RRP of £539.99 / €719.99.
