Canon Patent: 13-21mm f/2.8 Lens For EOS R Camera System

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.
