I work for a church. We shoot a prayer service weekly. The pastor stands in the frame and is in focus. The pastor turns and kneels, face away from the camera now. Camera stays in focus for 10 seconds and then drifts out of focus. Nothing in the frame is in focus. Happens every two to three weeks. We use auto-focus with face detection.
What can I do to prevent the camera from drifting out of focus? Thanks for your ideas!
