maverick75 Cream of the Crop More info | Apr 29, 2013 16:27 | #1 When I have my 560 II turned off on my hotshoe the camera will not take a picture, it just gives me a Error 99. If the flash is on it will fire normally. - Alex Corona Sony A7, Canon 7DM2/EOS M, Mamiya 645/67

Either is not a good condition.

Apr 29, 2013 17:12 | #4 Thanks 110yd! I looked up this problem and found someone mention something similar as a safety sync, but the 560 II is known to be safe for digital. I tested the voltage prior to even using it, I'm going to test it right now to see if it's giving off power while off. - Alex Corona Sony A7, Canon 7DM2/EOS M, Mamiya 645/67

Regards, 110yd I just tested the flash with my multimeter and it's not giving any power while off, the hotshoe is also not giving off anything. - Alex Corona Sony A7, Canon 7DM2/EOS M, Mamiya 645/67

I have no idea what design rules the folks at Yongnuo followed, but when dealing with battery powered widgets, it is VERY EASY to get in to trouble design wise....A signal that is an input or an output can accidentally provide a path for current to flow if proper design rules are not followed....In your case, the flash is turned off, but I suspect that there is a path through the I/O of the flash that provides a low impedance to the signals in the camera....You would not be able to detect this type of issue measuring the voltage on the FLASH alone.
