EOS M50 Mark II losing settings

[mbrewis]

We are currently using 10+ M50 Mark II camera setups that communicate via USB using the EOS SDK in Windows and gphoto2 in Linux (we are taking pictures). Each camera is setup the same way when they leave our facility. In the field we are noticing that settings (ECO and sleep settings) have been changing without any interaction. As a result the cameras have been erroring out on average once to 3 times a day. At which time the camera's have to be restarted in order to work again.

Has anyone run into this issue or know of how settings could revert to a default state?

Thanks

Hi mbrewis,

There are a couple of things to check with an issue like this. The first is to double check the mode dial isn't being changed. Some camera modes do not retain settings from other modes. So like if the settings were dialed in on a custom mode and then it got changed to P, Tv, Av, or M the settings would not transfer over. 

Another thing to double check would be the battery on those cameras. If the battery fully loses charge, or if the camera is left off long enough with no battery loaded, that would cause the capacitor that holds onto the camera settings to lose charge. When that happens the camera will revert to the factory default settings when it is powered on again.

Hi Hazel_T,

Thanks for your response, both of your suggestions were very helpful as it is very possible a tech could make a change to the dial mode and since we have direct wired batteries an interruption of power that is long enough to drain the capacitor would also cause our issue. I will mark this as the accepted solution.
