Patent: Canon Curved Aperture Diaphragm

Here’s another patent filing picked up by egami:

(translated)
Patent Publication No. 2014-13363,2014-13365

  • Publication date 2014.1.23
  • Filing date 2012.6.6


  • Canon patents

  • The iris of the dome-shaped

  • If I’m reading this correctly, if the aperture follows the curvature of the glass you end up by saving some space which can lead to more compact lenses, if not for the M line, than perhaps we’ll see some smaller EF-S lenses.
