I now have to take it off camera to make any adjustments to remote or menu settings, once the thing drops a flash you have to go very close to reconnect
Argh, and I finally ordered it last week after so many positive reviews, esp. since I need the af assist over the Canon :-( ... did it work at first and then break, or didn't you realize the problems after purchase?
What's exactly the problem when changing settings on camera? Last not least, did you contact Yn with the flash connection loss problem to get a fixed fw?
No it has behaved pretty consistently since I had it, it is just longer days in a pro environment that it really starts to fail. Normally after over two hours of constant use. My initial testing didn't show this up, after all, who takes test pictures for hours........
As for changing the settings on camera, in my first comments I noted that the buttons and wheel were easier to move than the Canon ones, I assumed when the screen changed it was because my thumb or finger had touched a wrong button and exited me from the menu, turns out that isn't what is happening, it seems something in the connection with the camera is exiting me from the menu, sometimes one second after entering it, but as time goes on much less than one second elapses before the screen stops responding; yet if you take the YN-E3-RT off the hot shoe you have complete use of all buttons for as long as you want and you are never locked out of the menu. It is 100% to do with being on camera.
I did not contact Yongnuo this time, I did previously about the Remote Release bug whereby the remote flashes are not fired with pre 2012 cameras yet they are with post 2012 cameras, and with the ST-E3-RT with both. They said this was designed in and they categorically refuted that the YN works differently on post and pre 2012 cameras in Remote Shooting mode, but it does.
The flash connection is relatively new, but it has happened on three shoots now, I shoot some real estate and have 600-EX-RT's inside the property and control them from outside, with the ST-E3-RT this is effortless and 100% reliable, however with the YN-E3-RT it is not so and when they do stop talking I have to take the YN off the camera and walk it back into the property, often the same room, to get it to reconnect.
I believe many will never have an issue with the YN, I probably work them harder and longer than most would and the reliability seems to drop off as shoot time goes up. For pre 2012 cameras and non critical/short term use they are still a way better buy than the ST-E3-RT, for longer shoots or with post 2012 cameras just get the Canon.
