I have noticed that in unwanted cameras, unique sensors help to focus automatically. The sensors with some camcorders change in contrast, while others use a beam associated with infra-red (IR) light, especially in low light. Higher spec cameras occasionally use a mixture of both techniques and could have Face Priority AF where the photographic camera can ‘See’ some sort of face and focus only on that. Many thanks for sharing your thinking on this blog.
