Canon Patent Application: Canon RF 135mm F1.4 We know that Canon is going to make some more jaw dropping primes, and we've discovered buried in a related patent application the design for a Canon RF 135mm F1.4. This would make an excellent upgrade to the lengendary Canon EF 135mm F2.0. From the Patent Application; Focal length: 131.00 F-Number: 1.41 Half angle of view: 9.38 Image height 21.64 Total lens length 182.28 BF 13.87 This I believe will be one of the lenses coming out in the near future. It essentially completes the professional prime portrait lens kit.
