7D Mark II Reported Issues

[privatebydesign]

That is the main reason I sold my YN-E3-RT, and the fact that the firmware updater was PC only, not Mac compatible.

Hi,
another flash problem I have, may the third party problem too.
I use the YongNuo YN-622C ETTL radio triggers on my 7D before and after getting the 7D II they didn't work
Nearly all exposures where full flash exposures.
If I set the flash control to manual it worked, but ETTL, even with a Canon 430EX II flash on the YN-622C device didn't work.
I would say Canon changed the wireless flash control interface a little bit, so third party flashes could have a problem.
In my test the pre flash for ETTL was too bright, so the camera will send a full flash needed command too the flashes and the picture is overexposed. With the use of the internal flash as wireless master the pre flash isn't that bright.
It's not a Canon problem, but I think it's good to know.

In my thread http://www.dpreview.com/forums/thread/3747630#forum-post-54671707 a user say that the Pixel King ETTL flash devices have the problem too, but this devices have a update function so they may be work later.

Curious if these 3rd party flashes work ok when they are attached directly to the camera or is it only when the are used as slaves?

Hi East Wind Photography,
the YN-622C is a radio trigger only.
It will be attached to the flash or the camera itself.
I tested the YN-622C on camera with on YN-622C flash and this seems to work, but on camera flash is the least useful for me.
Still thinking that the wireless flash data transfer protocol from canon is slightly changed on the 7D2, so 3rd party flashes make a false preflash.
I have a similar problem with an older Nissin flash, but this was on 7D not 7D2.
Just curios that the original canon gear have no such problems, but this is original vs. 3rd party.

Hi,
I hope - it's not so ...
622C is only responsible for the data transfer.
I can't see difference between on-camera and off-camera flash mountig
Control signals are the same and the YN622C passes on what he gets.
I've used 622C on 7D 5D3 and 6D - no problems. Why now on the 7D2?

Decided I'm keeping the 7D2 so I unwrapped the new LP-E6n battery. At first my Watson Duo charger refused to recognize it but after charging for a bit on the LC-E6? I was able to get it going on the Watson. Anyway, man that thing is slow taking a charge. My canon LP-E6 has gone from 45-95% in the same amount of time as the LP-E6n has gone from 45-65%. Hope that improves with recharges.

Let us know how that goes. I think it may also be the same issue as when the batt drains. The charger needs to learn the charge rate after several cycles. The new batts are higher capacity but not that much higher.
