We’ve been instructed that some “crazy” lenses had been coming to the RF mount, and here’s a patent uncovered by Northlight that matches the invoice.

Canon seems to be engaged on a quick portrait zoom for the RF mount, with the quickest of the bunch being an RF 50-80mm f/1.1. The variety of lens parts within the lens design is exceptional.

Canon RF 50-80mm f/1.1:

  • Focal size: 51.50mm 64.17mm 82.52mm
  • F-number: 1.13 1.13 1.13
  • Half angle of view: 22.79° – 18.63° – 14.69°
  • Total lens size 220.20mm 225.05mm 224.20mm
  • BF 6.51mm 6.53mm 8.64mm

Also included on this patent are optical formulation for a RF 50-80mm f/1.2, RF 50-80mm f/1.4, RF 50-80mm f/1.6 and a RF 50-80mm f/1.8.

We anticipate some new lens designs to be introduced within the first half of 2020. Keep in thoughts, simply because there’s a patent, doesn’t imply we’ll truly see this as a product.
