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.

        The remote transmitter lets one get the flash unit off the camera and still have complete and easy control right from the transmitter. Easy to use and allows great creativity.

          I got this transmitter and a couple of 600's, they work amazingly fine, is really easy to control the power on the flashes just using this transmitter. Ii was worth the investment.

            I have studio strobes, but have started moving outdoors. I had one 600EXRT flash and took the plunge for a 2nd along with this transmitter.

            Still learning how to shoot in daylight, after cutting the cord.

            Why does it have to be so expensive? Equally frustrating is why the 1Dx doesn't have the capability built in.

                                    The convenience of a radio control system for multiple strobes is terrific and Canon's transmitter seems to do a decent job of it.

                                    My main complaint is that the entire user interface on both transmitter and strobe should be more streamlined. Changing power levels on off-camera strobes takes too many button presses and dial turns. That doesn't make sense considering the whole purpose of this is to make things quicker and easier.

                                    Also, changes made on the transmitter don't register on the strobe's display until you test fire them or take a shot.

                                      This is very useful. I had one Canon speedlite and bought two more that it came with. When you do not need or want a speedlite on top of your camera, this frees up all other speedlites to be placed on stands. Its is light weight on non bulky. It also saves your camera battery charge and can eliminate the need for a sync cord. The only reasons not to get one is to save money if you do not plan to do much off camera flashing.
