Canon Updates Speedlite Transmitter With New ST-E3-RT Version 2: ST-E3-RT(Ver.2)


Canon has introduced the ST-E3-RT(Ver.2) - an update of the popular ST-E3-RT transmitter which enables wireless flash synchronisation and multiple control of Speedlites positioned up to 30m away.

The ST-E3-RT(Ver.2) supports key features of the recently introduced Speedlite EL-1 and also enables new capabilities when using previously launched RT Speedlites  - including wireless (radio) second-curtain synchronisation. Other new features of the ST-E3-RT(Ver.2) include support for the Speedlite EL-1’s low-power 1/8192 micro flash and for photographers who use manual flash, the transmitter boasts a new FE Memory mode.

Through introducing radio wireless transmission and second-curtain synchronisation, the ST-E3-RT(Ver.2) releases the flash at the end of a long exposure. As a result, it helps photographers produce natural-looking images when capturing moving subjects. The ST-E3-RT(Ver.2) offers this feature as a new wireless option, giving users flexibility in a range of shooting scenarios.

When shooting with a large aperture and/or high ISO speed, the flash level can often overpower the subject and scene. This forces the photographer to change settings or set up, ultimately losing the look they desired. When partnered with the Speedlite EL-1, the transmitter’s 1/8192 micro flash adds subtle nuances of light without disrupting the atmosphere and ambient light reflected on set. This feature is perfect for fashion and portrait photographers looking to capture scenes with a natural atmosphere.

Building on the original transmitter’s flexible qualities, the ST-E3-RT(Ver.2) supports FE Memory – offering a quicker and more convenient manual flash set up. Alleviating the need for multiple test shots, professionals now have the option to perform an initial shot in E-TTL mode, capturing the E-TTL flash settings. Users can then switch the Speedlites to manual flash to allow for manual adjustments where needed – all whilst retaining the original E-TTL settings.

Canon Europe is also providing a chargeable update for existing ST-E3-RT users. Those with the transmitter can send it to one of the listed Canon Service Centres to be upgraded to include the new additional features and capabilities of the ST-E3-RT(Ver.2). 

The Canon ST-E3-RT(Ver.2) retails at £289.99 / €329.99.
