I have custom shooting modes C1 and C2 set to specific settings with auto update disabled. If I change a setting, such as exposure compensation, the exposure compensation resets to the programmed setting (zero) some times and I don't know what I am doing to cause the value to reset to the saved value for the custom shooting mode. I have NOT turned the camera off and my tests indicate that the camera going to sleep does not reset the exposure compensation. My question is, what actions cause the settings I change during a shoot when in a custom shooting mode to reset to the saved values? Thanks.
