A patent showing how Canon could improve image stabilization in the future has appeared. It looks like Canon is trying to add a second image stabilization group to lens construction to improve its 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.
