A patent showcasing a host of optical formulas from Canon has appeared over at Canon News. These patents deal with small focusing groups that allow for light and fast autofocus performance, perhaps more geared to STM than to USM motors being used.
Optical Formulas Covered in the Patent: 11-22mm f/4-5. 6 24-70mm f/2. 8 35mm f/2. 8 18-150mm Read more. . . . canonrumors.com

Thanks to improvements in sensor design, iPhone and Android smartphones are gaining traction with enthusiast and professional creators. However, one area that has lagged behind developments in imaging sensors is image stabilization.
This patent application (Japan 2023-125903) has a lot of esoteric fast zoom lenses in some very nontraditional focal lengths. Many of the embodiments are missing the image height, however since we also have the half angle of view, we can work backward to verify if these lenses are meant for full frame or for APS-C.
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.
It's been a few years since we first started reporting on the possibility of an affordable “box” style cinema camera from Canon. For a while we were running with the name Canon Cinema EOS C50.
