New Patent: Canon EF 135mm f/2 Lens with Apodization Filters

Canon has filed a new patent for 135mm f/2 lens with apodization filters.

From Wikipedia:

Apodization is an optical filtering technique, and its literal translation is “removing the foot”. It is the technical term for changing the shape of a mathematical function, an electrical signal, an optical transmission or a mechanical structure. In optics, it is primarily used to remove Airy disks caused by diffraction around an intensity peak, improving the focus.

Take a look at the patent details below (translated by Google):

  • Release date 2016.12.22
  • Application date 2015.5.20
  • Focal length 130.98
  • F number 2.06

  • Image height 21.64
  • Lens total length 159.05
