Canon Patent - Improved Image Stabilization System

I have just returned from a rather successful wildlife photo trip to India. Witnessed two tiger kills from beginning to end on a Spotted and Sambar Deer plus Elephants and Monkeys mating, in addition to many new bird species for me. Trying to get back to writing my blog and catching up with the latest photography and NAB 2016 news. It will take me a week or two to get back to speed and precious little time to process the photos because by then, my next tour will be here already. I have a very busy Spring and Summer touring season ahead of me. You can see my works on

Egami has discovered a new Canon patent that may dramatically improve image stabilization on future lens design. It involves a second image stabilization system to enhance performance.

Patent Publication No. 2015-203862 (Google Translated)

  • Published 2015.11.16
  • Filing date 2014.4.16
  • Equipped with two vibration proof group
  • Shake detection, determine the amount of correction from the shooting information
  • Obtaining correction amounts of the two vibration proof group from the magnification ratio and the distance information of the lens
  • Going by the translation, it looks like the second image stabilization group would activate depending on magnification ratio and distance information read by the camera. I would assume this would be of great benefit to longer zoom lenses and super telephoto lenses.
