Canon News has uncovered a patent that appears to show RF mount cinema zoom lenses. It looks like these are cinema lenses because of their complexity and larger image height of 14mm. APS-C lenses from Canon tend to have an image height of 13.66mm.

This would be amazing glass! Just what I have been hoping for the new RF C line. Now I wonder what the size and cost will be. Nether will be small. Also, will these be fully manual lenses, or autofocus like the COMPACT-SERVO 18-80mm T4.4. Given the wide aperture I feel these will be fully manual, and therefore not cheap.

Typical Canon. Cripple Hammer their RF lenses to protect their EF line. Writing to the Executives at Canon Japan demanding a total and unreserved apology, and alerting the UK small claims court to my impending class action!

Does the Canon R mount support power zoom lenses? One of the benefits of purchasing a camcorder instead of an interchangeable lens video camera is that the camcorder's integral lens can be zoomed, including from a remote control.

After long time ago we were expecting the successor of EF-S 17-55 F:/2.8 iS.... if the RF 16-70 f:/2.8 will come as a cinema grade lens with AF and iS then this lens will be the one to rule them all (while ofc we r talking in regards of video and all around lens)!! Also Rf 18-55 f:/2.0 is an amazing patent! Canon bring these lenses please and let us to put them on our c70s and let the other ppl talk about a7/fx shit while we will create amazing images!!

What is more you can use them even on EOS 1D X series Camera and by providing external 12V supply you can use power zoom too.

Superb edition Canon - forging the RF system to be excellent FF still, video and cinema system. (Wished Nikon would have done a cine line cameras + lenses - likely to be too late - even if they started it now )

Please let any of these be real. This is the first step in making RF APS-C worthwhile.
