Off-camera wireless control

Pair the Canon STE3RT Speedlite Transmitter to other flashes with wireless radio transmission, giving you the ability to control up to 15 flashes over five groups. You’ll have complete wireless control to shoot up to 30 metres away for professional-level flash photography. With 2.4 GHz frequencies, it has no limitations to achieve the perfect light.

Customise your settings

Save time setting up your speedlight by making the most of the pre-set functions. Or, make it your own with custom settings. Set it up to automatically turn the power off or control the flash, sound or illumination just the way you like it. This flexibility makes complex lighting setups simple.

Backlit light for dim settings

The dot matrix LCD screen makes it incredibly clear and easy to see with the backlight, even in dimly lit situations. With an intuitive menu control and clearly laid out information panel, you can easily navigate the settings during your shoots even when your hands are full of camera equipment.

Get the right angle

Achieve more control with your shooting with a 360-degree transmission angle. Take your flash photography to the level it needs to give your shots that ultimate professional feel. You’ll be able to light your subject perfectly to create beautifully lit portraits with the ideal angle.

Compact, weatherproof and reliable

With a dust and water resistant construction, you can work just about anywhere with this speedlight. Whether it’s in the rough outdoors or exposed to moisture, you won’t need to worry about the weather while you’re shooting. It’s small and mighty, with a reliable construction that can take on any situation. It even runs on AA batteries so you won’t need to worry about carrying a battery pack.

Pairs with multiple flash meters

As it has controls similar to the new Speedlite 600EX-RT, this Canon STE3RT speedlite transmitter includes multiple flash metering options. You won’t be concerned about if it will work with your equipment. The hot shoe ensures reliable communication between camera and transmitter, so you can rely on it to get the lighting right.
