Trying to figure out why the exposure changes when the camera is set to manual with the AE unlocked. Exposure should stay constant regardless of environmental lightnig changes with manual settings and Auto Exposure lock off. Perhaps I have it backward and the AE needs to be locked? Searched the manual.... nothing.

I've place a signal beep at the time it changes to make it more clear.
Any thoughts?
