Canon continues further development of its miniature lenses for what appears to be smartphone applications.
This is a patent (USPTO) for the Canon 100-400mm camera/lens that can fit in the palm of a child’s hand.
This patent explains more about the camera, along with lenses that will mount to it. In theory, Canon could develop a range of different focal lengths that will attach to the camera unit.
Could this be the birth of a tiny new camera and lens system? I don’t know, but it’s definitely an interesting concept that appears to be deep into development.
