Canon Patent For RF 90mm f/2.8L IS Macro Lens (EOS R System)

Canon Patent

Hi Lows Note spotted a rather interesting Canon patent application (2017-108266).

The patent literature describes a 90mm f/2.8L IS macro lens for the Canon EOS R system. Two optical formulas are discussed in the patent literature.

Specification and lens arrangement of embodiment 1

  • Focal length: 97.00mm
  • F number: 2.92
  • Half angle of view: 12.57
  • Image height: 21.64mm
  • Lens length: 115.12mm
  • Back focus: 20.01mm

Specification and lens arrangement of embodiment 3

  • Focal length: 86.00mm
  • F number: 2.87
  • Half angle of view: 14.12
  • Image height: 21.64mm
  • Lens length: 115.07mm
  • Back focus: 15.93mm

Well, this is a patent application for a lens that may indeed hit the market (most patent applications never become a real product).

More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production in the next few years are these:
