I bought a camera from a local pawn shop and have been using it to shoot several kōans. While setting up for Kōan No. 31, I noticed that the camera's image stabilization feature is glitchy. In the video above, nothing was moving. The camera was erratically trying to stabilize an image that was already stabilized.
Note: Sometimes I forgot to turn off the image stabilization while shooting other kōans. You can see it in Kōan No. 76, for example. It looks like something is moving the camera.
