Canon has filed a patent in Japan that shows what appears to be a compact built-in teleconverter that relies upon external controls and internal actuators to provide photographers with quick access to various focal lengths. [Read More]
In this Japan Patent Application, JP 2023-118490, Canon is investigating creating smaller built in teleconverters for use in lenses that we would normally not expect to see a teleconverter installed in.
