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.

This transmitter, together with the 600EX II speedlite, is a match made in heaven. Easy to setup and use. Love that it is RF. It is a bit pricey, but definitely worth it.

Comments about Canon ST-E3-RT Speedlite Transmitter:

This transmitter, combined with 600EX, 600EX II, or 430EX III Speedlites makes setting up lighting (from simple to complex) a snap. It's so easy to setup the various groups (from ETTL to Manual to ratios to on/off) right from the back of the camera that you become inspired to try more creative lighting. Honestly, I've done things that I wouldn't have bothered to try before because going around to the various flashes and making changes was such a PITA, now I can do it in seconds.

The transmitter is very well built with Canon quality and very easy to use and carry. It's easy to mix in studio strobe as well simply using those as optical slaves. Best of all, you can hide your Speedlites anyplace you like as they no longer require line of site.

A couple of rebuttals to some of the other reviews:

1. No focus assist beam. No, but the primary reason for using a transmitter is NOT because you're in a low light situation. I rarely am setting up RT Speedlites due to low light. Most of us use them to control light which is very different. For the few times when a focus assist beam would have been necessary in the past, the -3 EV focusing (-4 EV in live view) on my Mark IV has easily handled the task.

2. "Get a Pocket Wizard it's only $200". The Pocket Wizard has all sorts of issues with Canon Speedlites, doesn't support group mode in most versions (what's the point) and aren't nearly as reliable with most due to RF interference. Enjoy the $70 savings, over the years you'll use the RT Speedlites and transmitter, it's pennies.

3. "You'd be better off buying a 600EX instead, as you'd also get a flash". That's bad advice as you're doubling your cost and you've got something much, much larger you have to keep on your camera. However, IF you'd like to have a flash on camera and want the focus assist beam AND want to save money, then get a 430EX III-RT. It'll give you all the features of the transmitter, and save you $30. I still prefer to have the ST-E3-RT on camera for the smaller size, but the 430EX III is a decent alternative.

Bottom line, if you regularly shoot multiple light setups with Speedlites, you'll love using the ST-E3-RT.

Pricey but worth

By Stanley

Comments about Canon ST-E3-RT Speedlite Transmitter:

If you own the newest Canon Speedlite off camera this is the unit to get. RF is much more reliable than IR and doesn't not rely on light of sight like the older versions of the transmitter. Yes it is pricey but worth it in terms of convenience and dependability. I can even "burry" the stone inside of a softball and the signal gets thought. Plus you can make many of the needed adjusts to the speedlite from the transmitter and camera very easily. I'm working with the latest Canon speedite and DSR. I don't know how well it would work with other brands of equipment

Comments about Canon ST-E3-RT Speedlite Transmitter:

BUY THIS! After going cheap with off-brand transmitters/receivers and struggling for years, this little tech gadget dream is amazing. The power save mode on the 600ex rt speedlite before used tot annoy the hell out of me, because with the off-brand units, myself or my assistant would have to walk all the back over to light stand and turn flash out of sleep mode... now with the ST-E3-RT Speedlite Transmitter, NO NEED to do that!!! HECK YES!! Just hold my shutter button half down and I'm ready to go :)

I love working with this trigger and off camera flash with my two canon 600 ex rt flash. The control at my fingertips and ability to change power so quickly and easily is great. The reach meets my needs and ability to trigger through obstacles is priceless. I bought a second one so I did not have to switch off when using two bodies on a shoot. Worth every penny.

Excellent with the 600 series speedlites. Pricey for sure, but so far dependable. Only bummer for me is it doesn't have second curtain flash feature. Use it a lot for landscapes. Obviously not a deal breaker, but would have loved to have it. Otherwise no complaints.
