After waiting MONTHS my ST-E3-RT has come in from B&H, meanwhile I've been using 3 600RT's on a 5DMKII.
Knee jerk reaction you see to the Canon RF system is along the lines of too expensive. My take is sure you can get cheaper setups, but find one that is this minimalistic, feature filled, and reliable. I'm not paying an assistant so putting out a little more for a tiny kit I can put in a small bag pays for itself, and it always works.
- Now with the complete package I'm completely flabbergasted and happy with how well these work.
- The ST-E3-RT is much smaller than I expected, it doesn't add much of any weight to the camera and I'm glad to not have a monster heavy flash up there!
- I like that the display is horizontal - easy to access and tweak while shooting
- It was an issue to know which of my flashes was the master, with the ST-E3 it's obvious
- I don't miss the focus assist light at all. Your milage may vary, but for me that was never very useful anyhow (doesn't help in full darkness, and takes too long in partial)
- I still have my 580 which is the flash I throw up there when I just want a shoe mounted flash (not often hopefully, just a little fill when outside)
- Of course it works flawlessly
