Canon's flagship Speedlite 600EX-RT delivers the ultimate in high-performance reliability

Canon today announced its new top-of-the-range flash model: the Canon Speedlite 600EX-RT. Featuring both radio and optical communication capabilities, the new unit opens up a range of multi-flash shooting possibilities, delivering even greater quality, reliability and flexibility for professionals and enthusiasts.

Building on and replacing the 580EX II, the high-performance Speedlite 600EX-RT enables multi-flash shooting in a variety of complex and diverse lighting situations, guaranteeing consistent and optimal results.

"The Speedlite 600EX-RT sets a new benchmark in flash technology," said Rochelle Mora, Brand Manager – Imaging at Canon New Zealand. "The Speedlite 600EX-RT delivers a world of multiple shooting opportunities for photographers, saving them time while giving them greater control, flexibility and the creative freedom they need in complex lighting scenarios.”

New and improved features

The Speedlite 600EX-RT incorporates radio communication capability to deliver more flexible and reliable wireless links between the flash and camera body. When using a radio link, the Speedlite 600EX-RT can be positioned at distances of up to 30m from the camera; it can also be successfully used in a diverse range of situations where an optical solution would not function, including when the flash is positioned behind or facing away from the camera, or in a soft box.

Also announced today is the Speedlite transmitter, ST-E3-RT, that has been newly developed for radio transmission wireless flash shooting. When combined with the Speedlite 600EX-RT, it enables advance wireless flash shooting that makes the most of the convenience of radio transmission. It enables a new shooting style using 2-way transmission between the master and the slave units, and up to 5 groups of slave units can be controlled (15 units total).

Combined with the Speedlite transmitter, the Speedlite 600EX-RT also supports improved multi-flash shooting, thanks to bi-directional communication between master and slave units. Additionally, slave unit settings can be changed directly from the master unit, enabling photographers to manipulate lighting levels remotely as required.

The unit's inbuilt wireless communications capability also allows the camera's shutter release to be triggered from a slave unit, even when that unit is not directly in front of the camera.

For photographers pursuing even more complex shooting and lighting scenarios, the Speedlite 600EX-RT can simultaneously release the shutters of up to 15 slave cameras also fitted with Speedlite 600EX-RT units, thereby allowing a subject to be captured from a variety of different distances and angles.

The Speedlite 600EX-RT is also equipped with a range of filters, allowing the colour temperature of the flash output to be adjusted to suit different shooting requirements. Output can be adjusted to match ambient lighting conditions, thus achieving greater and truer colour tones. A filter holder is included and extra filters are available.

Optimum reliability and performance

To ensure the Speedlite 600EX-RT can deliver results in diverse shooting conditions, Canon has increased the unit's output to provide constant light coverage at focal lengths of between 20-200mm. Combined with an output of Guide No 60, this ensures even, corner-to-corner lighting when used with wide-angle and telephoto lenses.

Understanding that reliability and durability are key priorities for professional equipment users, Canon has also significantly redesigned the unit's hot shoe contacts and improved the signal transmission system. Heat resistance and durability have also been improved.

The Speedlite 600EX-RT also complements the sophisticated features available within Canon's new EOS 5D Mark III and top-of-the-range 1D-X. The unit's AF assist beam covers all of the cameras’ 61 autofocus points and is effective from up to 10 metres from a subject.

Exposure metering has also been improved. The unit's stable E-TTL metering function uses a face detection algorithm that detects face colour and then optimises flash output to optimise the exposure for the subject.


The Speedlite 600EX-RT will be available through Canon New Zealand Authorised resellers from late March. It replaces the current Speedlite 580EX II model.
