Chosen Solution

The auto focus isn’t stable. the camera keeps “seeking” to focus. It even happens with manual focus turned on, and instant focus, face detection and image stabilization turned off. I cant figure out what is causing it. it is happening on both my hf s10 cameras now.

Stupid question, but have you cleaned the lens lately? And I mean with microfiber chamois, not a shirt.

The only other thought at the moment is, if it’s full manual and still trying to focus, the sensor might be loose inside the camera body.
