Canon has announced an update to its Speedlite Transmitter ST-E3-RT. Like the original, this transmitter enables wireless flash synchronisation and multiple control of Speedlites, positioned up to 30m away. It also supports key features of the recently introduced Speedlite EL-1 and 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 the transmitter boasts a new FE Memory mode, offering a quicker and more convenient manual flash set-up.
