Canon ST-E3-RT V2 Speedlite Transmitter

The updated ST-E3-RT V2 Speedlite Transmitter from Canon can fire 15 flashes (or 5 groups) simultaneously, taking full advantage of pro-level flash systems such as the Speedlite EL-1, 600EX-RT, and 430EX III-RT. You are granted reliable and efficient 2.4GHz radio-controlled, two-way wireless transmission within a 30m radius. As the successor to the widely popular Canon ST-E3-RT, key upgrades have been made to include wireless rear curtain synchronisation to replicate dynamic subject motion, as well as a convenient minimum power range of 1/81922. This enables extreme low-light shooting, whilst the intuitive FE Memory feature gives you the ability to lock in an E-TTL flash exposure level - even when utilising a multi-flash setup. Further access is granted to 8 available custom functions and 3 variants of personal functions. Canon has prioritised user-friendly navigation with a clearly labelled info panel and tactile function buttons - tailor-made for professional flash photography.
