| p.1 #4 · Sell Pocketwizard Flex TT5's and buy Yongnuo 622c's? |
...while the PW's CE versions were apparently not available or licensed for US, I bought the CE on purpose because people weren't having problems with the CE versions and Canon flashes. I never had anyone complain or come to hassle me about any frequencies in the time I sued them, so I don't think I was ever in in jeopardy of being arrested.
Not being arrested is not the same as operating legally. Those frequencies are not legal for use in controling flashes in the USA. Period. End of story.
...I really don't know why the frequency was an issue, but adding a sock wasn't even an option when I got mine, and seemed like a really bad solution.
Some Canon flashes emit radio frequency interference at the PW USA frequency, and can block the receiver from getting a signal if the transmitter is at enough of a distance that the signal strength is reduced. (Which in the case of really bad Speedlites is as little a 20 feet, I'm told.) The "sock" and the later hard shield are used to shield the receiver from the RFI.
...Do you know if I would be losing any features by going to the Yongnuo product? Can I still control studio lights with them?
You can trigger studio strobes with the Yongnuos, but not control them as in adjusting power, changing modeling light mode, etc.
The YN622 has both a hot shoe and a PC jack, so just about any light can be triggered in sync, but as of now full control is only for shoe-mounted Canon-compatible flashes that work with the camera's flash control menu (and of course only with newer cameras that have that menu).
For example, the YN622C has only limited functionality with my 580EX no matter what camera, and my 580EX II and 430EX II can't be fully controlled by a YN622C mounted on my 20D. But if I put the YN622C on my 7D, I have full control of the 580EX II and 430EX II.
