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.

  1. 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.
  2. 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!
  3. 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.
  4. 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!!
  5. RF 16-70 T2.8 Cine Lens? For FF that would be awesome :love::love:!

    Image height is given as 14mm, so it wouldn't cover FF sensors. Probably for Canon's Cinema cameras, which have sensors with a diagonal of 28.2mm

    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.
