Canon seems to be very active lately in filing patents, from the obscure to the downright vague, as the CanonWatch blog has found. A few weeks ago, we got word that Canon has filed a patent for a 400mm f/5.6 mirror lens. Just before the year ends, there's news of another freshly filed patent that would surely be very useful to photographers. It involves better operation and lesser battery consumption during wireless communication.
