<p>Canon has filed a patent that shows the sensor moving to improve contrast AF, as you can see in the image above from Northlight Images, the sensor moves back and forth.</p>

Add Image Stabilization to that and many of us will ignore whatever the cost will be. ;D
Pentax and others have been doing that for years and although the K-1 isn't a huge jump, it would be nice to have IS available to our primes without IS. I own a tiny bit over $10K in lenses for work and it always stings that none of them have IS. :-\
PLEASE Canon put IS in the sensor! ;D 8)

Very interesting. Thanks for posting.

I'm quite amazed at all the different things that can be achieved by making the sensor move other than image stabilization! The Pentax K1 sensor has me intrigued and now this!

They can do tilt and make tilt-shift lenses obsolete xD also rexaling assembly tolerances

Tllt shift lenses won't become obsolete due to this.

At the moment TS lenses move the image circle by about 12mm in each direction, (24mm movement overall).. To do this they have a huge image circle vs normal lenses (~68mm vs 44mm), so even if you could move the sensor by +/-12mm in each direction then you'd run out image circle.

If there were Tilt-only lenses then it might make a difference, but as there aren't it doesn't matter.

TS lenses are inconvenient.
It's possible to make shift perspective change in PP rather than using lens with more coverage. Olympus even has this function in-camera for framing via EVF. Also, when you shift lens you're using its less sharp part of image.

don't disagree.

All true but this has absolutely nothing to do with the patent.
