Detailed Features

Shoot faster and for longer

The Speedlite 600EX II-RT delivers an uncompromising performance, making it an ideal companion for the EOS-1D X Mark II. Fire up to 50% more flashes continuously, compared with the Speedlite 600EX-RT, and add the CP-E4N battery pack for an even longer bursts.

Reliable performance on- and off-camera

An improved flash-control algorithm helps prevent overheating, and Quick Flash allows the Speedlite 600EX II-RT to fire even if a full charge hasn’t yet been achieved, so you won’t miss that unique moment. A zoom and bounce head ensures that flash coverage matches the lens in use, and allows light to be reflected from walls and ceilings for a more natural result. The Speedlite 600EX II-RT is weatherproofed to the same level as the EOS-1D X Mark II, so you can keep shooting even when conditions get tough.

A Bounce Adapter is included for softer lighting when shooting portraits and clip-on coloured filters help when balancing flash with ambient light.

Creative off-camera lighting from any direction

Simulate light coming from any direction by positioning the Speedlite 600EX II-RT off-camera. Fire it from up to 30m away, using built-in radio or optical control and an optional wireless trigger, the Speedlite Transmitter ST-E3-RT. Multiple Speedlite 600EX II-RT can be used together (individually or in groups) and can be combined with other Canon flashes, like the Speedlite 430EX III-RT.

Powerful performance, with guide number 60 (m, ISO100)

The Speedlite 600EX II-RT packs plenty of power, so you never be left frustrated. It’s ideal for lighting large spaces, and bouncing light from walls and ceilings for a softer, more natural result. A Bounce Adapter is included, which softens flash light even more. The unit recycles silently in as little as 3.3s, and the optional CP-E4N battery pack shortens this time even further. 

Easy to use, with intuitive controls and an informative display

A customisable control dial allows quick adjustments when working under pressure, while a large, illuminated display shows relevant shooting information at a glance. The charge status of all wireless flashes in the group is shown on the display of the master Speedlite 600EX II-RT unit.

I had a cheap flash gun before this and thought it would be difficult to justify £500+ for this.

However after using is for a few weeks now, wow what a difference. My images have improved massively, especially in low light. I can set my ISO to 100-200 and the gun does the rest.
It is a huge price to pay, added to that you then have another £250 to pay for the radio transmitter. Although it is worth the spend.
