Canon has announced the ST-E3-RT Speedlite Transmitter, price tag £289.99 / €329.99, which allows for wireless flash synchronisation and multiple control of Speedlites.
An update to the previous ST-E3-RT, the second version of the transmitter can provide wireless control from up to 30m away and enables new capabilities when used with older RT Speedlites, such as wireless second-curtain synchronisation.
The new ST-E3-RT also supports the Speedlite EL-1’s low-power 1/8192 micro flash and offers a new FE Memory mode for quicker manual flash set up.
Canon is also providing a chargeable update for existing ST-E3-RT users. Those with the original transmitter can send it to one of Canon’s official Service Centres to be upgraded with the new features of the ST-E3-RT(Ver.2).
