A new Canon patent for in-body image stabilization has appeared, and it looks like it is being worked on for DSLRs as well. This is the first time we've seen evidence of IBIS appearing in a mirror slapper.
Northlight says this patent deals with compositional issues and vignetting that could arise when the sensor moves for stability.
Could we see this in an upcoming DSLR? I think that would be a good thing for the EOS lineup, perhaps we'll see it in the upcoming EOS 90D or EOS-1D X Mark III.
