I have an odd webcam given by our company. When I plugged it in, I thought something was badly broken - it was just a giant blur. Messing around with the thing, I noticed my hand came in focus. Turns out that I had to manually adjust a ring around the camera to focus. Once I did that, the quality is crisp and clear, and I’m not moving closer and farther away from my desk, so I can see how autofocus isn’t needed. I think the simplicity of the design may actually be helping the quality in this case.
