What is your application? I cant think of many where the radio frequency wireless options aren't a better option than a cord. The YN622c are roughly $75 a pair on amazon.
I'll be doing a night photography workshop at the end of March. We've been instructed to bring "large and small" flashes. I'm planning on bringing all of my flashes: my 600rf, 430ex ii, and my two itty bitty Optex slaves.
The 600 can control everything optically, providing it has the line of sight required. I'm thinking I might want to get the 600 off of the camera to improve the line of sight to the other flashes. Or, I might just want to move the 600 off camera for better positioning of the light, while still being able to control everything else optically.
I could purchase the ST-E3-RT, and use the 600 off camera. But, I'd lose the use of the 430, and maybe the little Optex slaves. I haven't tested those with the 600 yet, but I think they might still work.
After mulling it over for a little while (and only having one 430ex ii), I decided to go with the 600RF for radio control instead of one of the other systems. The ST-E3-RT is on my wish list, and I will be picking up at least one more 600RF. I just really don't want to make that investment right now, however.
Could I use a pair of YN622c to RF control the 600 off camera, and then control the 430 optically? From what I've read, that can't be done with the ST-E3-RT.
