Here is another Canon patent application dealing with a lens for the Canon EOS R full frame mirrorless system.

Canon patent application P2020-30251A (Japan) discusses optical formulas for a 13-21mm f/2.8 lens for a full frame mirrorless camera system, i.e. for the EOS R system.

  • Zoom ratio: 1.58
  • Focal length: 13.40 17.30 21.20 mm  
  • F number: 2.88 2.88 2.88
  • Half angle of view: 58.23 51.35 45.58  
  • Image height: 21.64 21.64 21.64 mm  
  • Lens length: 150.15 136.89 130.04 mm
  • Back focus: 20.96 25.13 29.31 mm

This might well be a lens that goes into production, sooner or later.

More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production are these:
