×Canon ST-E3-RT Speedlite Transmitter
4 Day Rental Price:
$49.00
The Canon ST-E3-RT Speedlite Transmitter is Canon’s first wireless transmitter based on radio-signal technology. Key features include:
-
98.4-ft. range
-
Line-of-sight-free shooting with compatible Speedlites
-
On-board ratio and power-setting adjustment
Flexibility. The Canon ST-E3-RT Speedlite Transmitter gives users the flexibility of line-of-sight-free shooting when coupled with the Canon Speedlite 600EX II-RT, 600EX-RT, or 430EX III-RT. With a range of 98.4 feet and the ability to adjust ratios and actual power settings from the transmitter itself, the ST-E3-RT greatly simplifies elaborate lighting setups.
Intuitive Controls. The ST-E3 features a detailed LCD with clearly laid out, backlit buttons for full control of settings. Since the transmitter uses a radio signal, it’s only compatible with the radio-signal based 600EX-RT. Despite this, the ST-E3-RT transmitter still offers more control of its compatible Speedlite than any other trigger system out there.
