Auto-focus seems like one of the lesser useful features for webcam (or rather, the use case of a webcam seems to not require auto-focus that much) since the object distance remains largely the same for the duration of the video call, at least the video calls I'm usually in.
Maybe people have a different setup that I, but I usually remain the same distance away from my monitor at most times.
