While shooting during a recent vacation in Greece, the Finder / Monitor auto function ceased working on my camera. The LCD would not illuminate, but I could still use the viewfinder. If I changed the settings to either manual viewfinder or manual monitor, I could use either, but in the "auto" setting, the camera would not automatically switch between the two if I wasn't using the viewfinder. Then, mysteriously, the function resumed working later in the day. Battery power was not low. Has anyone else experienced a temporary glitch like this on your A7Rii? Any thoughts as to causes and/or quick remedies to restore the function?
