Canon's new flash system is a tour de force of flash technology with RF wireless control as the centerpiece. No longer do we have to choose between RF convenience and sophisticated features like high speed sync. We can have it all.

This unit is a 600EX-RT w/o the flash head. As such it is extremely light weight and obviously much smaller than the full flash. It only controls via RF so don't imagine using it with older, non-RT flashes. I tested mine with my 600EX-RT to a distance of 187 feet w/ flawless results.

Canon's new control layout, which is exactly the same on both the ST-E3-RT and the 600EX-RT, is greatly improved from previous speedlites in terms of the quality of the LCD display and the logic of the menu system itself. Once you get used to it you will never go back. Well done, Canon.

What is it missing? Some have complained that the unit lacks the ability to provide focus assist like the much older ST-E2. I wonder if any of the complainers ever used the focus assist on the ST-E2. It wasn't worth much. A flashlight or, better, a pen laser is far more effective in this role. It doesn't do second curtain sync. Wish it did. It doesn't appear to be firmware upgradeable. Wish it was. And I do wish the range was greater—just because I'd like it to have more range than I could ever imagine using. But, really, to call these concerns "minor" is to overstate their importance.

With five groups to work with, remote control of up to 15 speedlites, and two way communication between the system components, the ST-E3-RT is an outstanding component in what is now the ultimate flash system. I've been waiting years for Canon to upgrade their system. With the new ST-E3-RT and 600EX-RT they have a couple home runs.

For what it's worth, this transmitter does radio control off-camera speedlites... And that's all it does. Which is a bad thing. It no longer has the autofocus assist beam for focusing in low light conditions -- and low light conditions are possibly a principal reason you're using this equipment. It no longer has the optical transmitter function -- and some of your speedlites may be legacy devices. The interoperability of this device is lacking with other Canon and non-Canon flashes currently on the market; and these flashes will continue to be on the market for a long time.

Frankly, it makes a lot more sense to purchase a 600EX-RT and use it as a master transmitter with the flash set to not discharge on exposure (yes, you can use the 600EX-RT as a low-light autofocus assist or transmitter without flashing.) The 600EX-RT gives you the same master transmitter controls as the ST-E3-RT, but in addition you get the autofocus assist beam, a backwards compatible optical transmitter capability, and a flash bulb. For just a little bit more in price.

And what about the Pocketwizards? This has virtually the exact same functionality as a Pocketwizard, but the Pocketwizard transmitter only costs two hundred dollars. Really. This is a no-brainer. Skip the ST-E3-RT and wait for Canon to release the Mark II update that also includes the autofocus assist beam and the legacy optical transmitter functionality.

Comments about Canon ST-E3-RT Speedlite Transmitter:

I have a Canon 4300 EXIII speedlight and I like staying within a family of products, so far so good. :)

I would love to have seen a remote trigger with this, but it is what it is.

Great product

By Andre

from Undisclosed

Comments about Canon ST-E3-RT Speedlite Transmitter:

I'm very impresses wither the design and interface of the unit. The unit is well built. The only draw back is that it has limited usage with the rebel T5. Group mode will not work as it would with later models. I wish that bit of information would have been listed within the product description as it would have influenced my purchasing decision.

Perfect to use with my 630 EX-RT flash! Enabled me to use off camera flash for better lighting... looking forward to building my supply of flashes that will all be able to be controlled by the ST-E3-RT transmitter! Sometimes, technology can be so fun...

I've been a Canon shooter for more than two decades. The ST-E3-RT is just another example of professional-grade equipment. I use it with two 600EX-RT's. Flawless!

Comments about Canon ST-E3-RT Speedlite Transmitter:

I am using the ST-E3-RT to control Canon 600EX-RT Speedlites in a small at home studio. The menu layout duplicates the 600EX-RT and in that regard is easy to use. So far I am very pleased with the product. I suppose the only negative would be the price as compared to the equivalent Yongnuo Wireless Speedlite Transmitter.

    Necessary addition to canon 600 flash! I recently bought the flash and the trigger together. They allow me to use the radio technology. They work great together. It's a must have if you buy the flash.

        Comments about Canon ST-E3-RT Speedlite Transmitter:

        This is a fantastic transmitter. I've only been using it for a short time but already I am in love! It works seamlessly with the 600EX-RT and the interface is really similar to the flash itself so if you know how to use that, you'll know how to use this. It elevates your photography by allowing you to shoot with the flash off-camera and with the ability to control various speedlites through one piece of equipment. I had been thinking about getting new strobes but with the work that I do (mainly weddings, families, interiors), I can really do everything that I need with just this little guy and my speedlites.

          Makes flash shooting much easier. I no longer need for a PC cable and Optical flash. I can control all of the flash features from the Transmitter instead of having to navigate the camera menus to make changes. Easy to use, menu just like the 600EX RT
