Canon Patent - EF-M 55mm f/3.5 Macro

Canon EF-M line of lenses

Another new patent from Canon for the EF-M 55mm f/3.5 Macro was discovered by Egami, the Japanese blog.

Patent Publication No. 2015-215391 (Google Translated)

  •     Published 2015.12.3
  •     Filing date 2014.5.8
  •     Focal length 53.73
  •     F-number 3.50

Canon is working on a full frame mirrorless camera. It should not require an adapter to use the full line of EF lens like the current EOS-M mirrorless camera. There will be more EF-M lens coming in 2016.
