Canon 70D using Canon 600EX-RT
I bought the new Canon 70D as it is compatible with Canon’s 600 EX-RT flash systems in wireless mode,
I had the Canon ST-E3-RT mounted on the camera and (2) 600 EX-RT on light stands and my camera on a tripod.
This is the first time I have experienced wireless intermittent firing and I was not firing rapidly as I had to set up each shot that I was doing.
I switched Cameras back to my Canon Mk IV and even my old 5D just to see if it would misfire’.
No misfires at all...there is something not right with the new Canon Cameras...most embarrassing as I had the VP of marketing looking over my shoulder.
Is there anyone using the same setup?
See my first review :)-

The Speedlite 600EX-RT is a terrific flash. I have only had it for a few days but taken a hundred inside and outside shots experimenting with its settings. Perfect exposure in all scenario's. Great addition.

best flash I have ever owned
I have been with canon since my AE-1 35mm. I have made the mistake of buying cheap flashes and suffered for buying them. When I bought my t4i, I decided to get a really good flash to go with it. Oh my goodness, I had no idea I could do the stuff I have been doing with this thing. The batteries have lasted way longer than any other flash I have had to date. The first real test came when I was taking pictures of a soccer game at night and was getting perfect stills (action mind you) as far out as the half field and beyond. I know the camera played a part, but I was lighting up a good portion of the field with this thing. It was also very quiet. I had gotten used to the whinning flashes as they charged up for the next flash, but not this thing. I also loved the fact that I could take pictures quickly with this flash. I normally have to play the waiting game for my other flashes to charge and get ready for me to take another picture. This thing has an incredibly short turn around time between flash cycles. I was able to take pictures in rapid succession. I was taking pictures, and got ahead of myself. I forgot I had a flash on my camera. When I realized how fast i was taking pictures, I had to stop and check the pictures, sure enough the flash had kept up with me. The flash locks down to the camera body with just the flip of a lever. I must say that, to this point, I have just been using the flash for basic photography. But, the way it has worked out so far, I am looking forward to discovering all that this thing has to offer. I know the cost is pretty high, but I got lucky with the price. I was at a Bestbuy at the right time. They had a 600ex-rt that someone had just returned. I got a great price break on the thing. I can't say that I have found any cons as of yet.

Multi Flash Set-up overexpozure
This is a reaction to the previous review below by njw1224
from Wheeling, WV. It seems that there is an over exposure problem when using multiple flash set-ups with the 600EX Rt/600EX.
This can happen if there are three firing groups - A, B, and C.
If a firing group C has been added and an over exposure results, avoid firing group C toward the main subject as this will likely cause the said overexposure.
Alternatively, eliminate firing group C, and lump the extra slaves (from the now defunct firng group C) to firing group B or A. This works 99% of the time even if you point all flashes to the main subject.
The phenomenon of over exposure in multi flash set-ups has
been mentioned in pages 87 and 112 of the 600EX RT manual.
