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:

    Initially considering third party radio flash transmitters because of cost, I am glad I spent the extra cash and stayed with Canon. I use the transmitter with the Canon 600EX-RT and improved the quality of images 1000% over on-camera flash and without a lot of complexities and fussy adjustments. Because of the similarity of the transmitter display with the flash display, and the immediate connectivity, I spent a very few minutes with the manual and was quickly up and running. I would have liked a lower price tag, but I don't regret springing for the Canon name. It helps assure compatibility with flashes and cameras with ease and quality of images.

    Works beautifully as expected and carries many features, but lacks an important one:6
    ~ optical transmition like the 600 EX-RT flashes have.~

    I can do w/o the AF Assistant lamp but there are still lots of 580 EXII around

      You can control all your flashes directly from it. And it also does not need the radio transmitter to communicate with the flash. Let your work much faster and more easy. I'm very pleased with the purchased. I recommend.

          Comments about Canon ST-E3-RT Speedlite Transmitter:

          I purchased 3 Speedlite 600EX-RT's and the Speedlite Transmitter. I upgraded from 580 EXII's. The radio's on these flashes are awesome and the menu system is greatly improved. The best part is being able to use the transmitter to control each of my flashes. This is helpful when I want to make changes during a wedding reception. I can make the change in a second instead of 5 minutes (with having to lower the stands to get to the flash units). I also love how the "master" color is different than the "slave" color. Less room for error that way. I highly recommend the transmitter AND the 600's. I'm sure I'll have even more good things to say once wedding season starts and I really get to dive in and use them.

                      Works like a charm in TTL or manual with my 600EX-RTs. None of the problems previously encountered with PocketWizard TT5s. Functions well at very close range or at 100ft inside and through several walls. Control of the flash settings work reliably from the transmitter too.

                        I've used it all, the pocketwizard flex system, plus II and III, cheap @ wireless kits,the Yongnuo YN622, the ST-E2, and this has turned out to be the perfect solution. I've only been using the ST-E3 (with 3 600EX-RTs) for a couple weeks, but so far I'm thrilled with the purchase.After a bit of light manual reading (a rarity for me), I was synced and ready to go. Though the menus on the ST-E3 and the flashes in wireless mode can be a bit complex, they are easy to get the hang of with some use. TTL works flawlessly and it is insanely easy to adjust individual flashes or groups on the fly. Though it takes a couple more buttons to adjust output with the ST-E3 than the simple dials of the Pocketwizard TT1 and AC3, I prefer the interface of the ST-E3, I feel like I know exactly what I'm going to get.This setup feels like the perfect location rig for me with a few stands and modifiers. I'm very happy with the purchase. Though the price can add up once you start buying multiple flash units, the simplicity and reliability of the setup is fantastic.

                          Works as intended. It doesn't send changes immediately to other speedlites, you have to half press shutter to send changes. Otherwise a nice luxury.

                          - Upgraded from a pair of Canon 580EX IIs speedlites

                          + What's great about this product:
                          - Fairly easy to use when you read the manual. (and I don't even like reading)
                          - Wireless capability frees you from a heavy on-camera setup AND extends the lighting possibilities
                          - The transmitter works amazingly with the Canon 600EX-RT and eliminates the need to add pocketwizards all the time.

                          + What's not great about it:
                          - It should've been built with a focus beam for low-light situations.

                              This is awesome. Controlling all of my Speedlites wirelessly without line of site, makes the setup easier and allows for a lot more creativity. Love it!

                                  Much more durable than the yungnuo - if you are planning to use this in all sorts of weather conditions (like I, as a photojournalist) this is the way to go. A bit complicated to use at first, but easy once you figure it out.
