Canon ST-E3-RT V3 Speedlite Transmitter (Ver. 3)

Maximize the capabilities of compatible flashes with the latest iteration of the Canon Speedlite Transmitter ST-E3-RT. This transmitter streamlines intricate lighting arrangements by enabling radio-controlled, two-way wireless communication over distances of up to 98.4 feet among a maximum of five groups or 15 individual Speedlites. Wireless Rear Curtain Synchronization is provided for capturing light trails and achieving motion blur effects in your photographs. With an extensive minimum output range, you can adjust down to 1/8192 for shooting in very low-light conditions. The FE Memory feature is particularly handy, allowing you to lock in an E-TTL flash exposure level, even in complex multi-flash setups, and retain it for subsequent use with the same scene or subject. The design incorporates eight types of custom functions and three types of personal functions. Featuring an LCD panel and backlit controls, operation remains straightforward even in dimly-lit settings.
