And yet another Canon patent for a lens for the EOS R full frame mirrorless camera system,

Canon patent application 2020-181169A (Japan) discusses optical formulas for an RF 80mm f/2.8 Macro 1:1 lens.

  • Focal length: 80.45 mm
  • F number: 2.90
  • Half angle of view: 15.05
  • Image height: 21.64 mm
  • Lens length: 123.69 mm
  • Back focus: 13.72 mm

Interesting lens I have to say. Let’s hope it goes into production.

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