The EOS M patents continue to flood in, this time we get a patent for an EF-M 15-50mm f/3.5-5.6 IS STM optical formula.

Patent Publication No. 2016-75742 (Google translated)

  • Published 2016.5.12
  • Filing date 2014.10.3
  • Zoom ratio 2.94
  • Focal length 16.00 27.43 47.04
  • F-number 3.62 4.50 5.82
  • Half angle of view (degrees) 37.55 26.47 16.19
  • Image height 12.30 13.66 13.66
  • Overall length of the lens 78.86 74.05 77.88

This definitely looks like a kit type of zoom lens from the upcoming EOS M body, which we expect to be announced before the end of 2016.
