Canon EF 35mm f/2 IS II USM Lens Patent Diagram
In a recently published patent application, Canon details a new 35mm f/2 lens. You can see the optical formula in the above diagram.
The lens construction is 104.5mm long, so it is quite a bit longer than the current model at 62.6mm. The patent also covers a revised image stabilizing system to the current EF 35mm f/2 IS USM.
It was filed on March 31, 2015. You can read it for yourself below. As always, let me know if anything else jumps out.
