Here is a new Canon patent. A RF 130mm f/2 lens for the EOS R full frame mirrorless system.

Canon patent application 2022-043436 (Japan) discusses optical formulas for a RF 100mm f/2 lens.

PROBLEM TO BE SOLVED: To provide an optical system which is compact and has various aberrations such as chromatic aberration satisfactorily corrected.

Example 1

• Focal length: 130.77
• F value: 2.06
• Half angle of view: 9.39
• Image height: 21.64
• Overall length: 132.51
• Back focus: 25.26
