One of the worst-kept secrets (I guess it’s not a secret anymore) is that Canon will be bringing IBIS to the EOS R system, we’re not sure if we’ll ever see it in the EOS M or EOS lineup, but it’s definitely coming for the RF mount cameras in the future.
Canon News uncovered Japan Patent 2019-087937, which talks about how Canon is going to implement collaboration between IBIS and IS equipped lenses. If Canon didn’t figure out a way for both systems to work together, I think adding IBIS would simply be a half-baked feature addition.
Part of the patent talks about the moving sensor for stabilization:
The imaging element 101 is movable in a direction intersecting the optical axis of the imaging optical system 210 (indicated by a broken line in the drawing) by a shift mechanism (not shown). For example, it is possible to shift in a plane orthogonal to the optical axis or to rotate in a plane orthogonal to the optical axis about the optical axis as a rotation center. In the following description, the case of shifting the imaging device 101 will be mainly described.
The patent further mentions that both the lens image stabilization and in-body stabilization are working together:
The antivibration lens 204 can be shifted in a direction including a direction component orthogonal to the optical axis by a shift mechanism (not shown ) at the time of antivibration. That is, it may be shifted in a plane orthogonal to the optical axis, or may be pivoted about a point on the optical axis.
Making these two systems work together likely isn’t an easy task, but once it does launch, I expect that it’ll be a great implementation of both technologies.
