Canon is working on consumer oriented lenses for the EOS R system, and this Canon patent application seems to confirm the commitment. An upcoming RF lens just leaked through a certification authority.

Canon patent application P2019-219679A (Japan) discusses the optical formula for an RF 24-300mm f/4-5.6 lens. We think it is an RF mount lens since the patent literature refers to a full frame mirrorless camera.

  • Zoom ratio: 11.77
  • Focal length: 24.72 90.83 290.86 mm
  • F number: 4.12 5.00 5.88
  • Half angle of view: 41.19 13.40 4.25
  • Image height: 21.64 21.64 21.64 mm
  • Lens length: 165.57 210.57 255.57 mm
