Here are my conclusions.
At first it took me a second to get these started, but then I realized I accidentally set them in the wrong mode (holding channel for 3 seconds putting them in mix mode).
-Currently they don't work on my 1d mark IV, but yongnou has contacted me and is working on a fix. They currently work on my 5d3 and my 7d. I honestly thought they'd work fine on the 1d and 7d, but oh well.
-The build appears roughly the same as the pixel kings, minus the weirdo shape the kings had. The locking ring seems nicer and the metal hot shoe appears beefier (from what I remember, I sold mine two weeks ago).
-the pixel kings came with a nice carrying case and cables. the YN622's didnt, I wish they did. Looks like I'll just have to find a way to safely transport them.
-Quick start up time / shoot time. You can see in the video I shoot with the transceiver (tx) off, then turn it on and shoot right away without any issues.
-Manual / ETTL ratios is very easy to control especially on the 5d mark III. This is exactly how I expected them to work.
-MIX mode i haven't gotten into yet, again, i JUST got them today and literally opened them, and started filming.
-haven't used these with any YN560's yet, but im assuming they work just like dumb triggers
-i CLEARLY need to read the manual.
-I wish there was a USB port for possible firmware updates.
-LOVE the fact that they are transceivers!!
-Didn't test long distance, but will this weekend at my wedding. Since it's on 2.4gHz i'm sure it will be fine.
