A previous camera of mine would sometimes act as if some spirit force was independently operating it. Quite a few times I would see the camera take a photo by itself, when I was a few meters away from the camera. In the post here you can see a video showing the camera taking 300 photos by itself, in 13 separate bursts. In the post here you can see the camera changing its settings by itself.
I have a new Sony A6100 camera because my previous model stopped working about two weeks ago. Today I again saw a case of a camera acting as if some invisible force was controlling it. After I took thousands of photos of falling water drops using a digital zoom of 1.9375, the digital zoom on the camera starting changing, just as if someone was turning the lens (even though I wasn't touching it). When I examined the photos, I saw the progression below occurred in a series of consecutive photos, even though I did nothing to cause it.
Photo Digital Zoom
I had to twist the camera lens to restore the previous digital zoom of 1.9375.
