I think there are two issues here.An AF engine has to move a group of lens elements within the tube of the lens
A tilt engine has
- to tilt the whole tube with all lens elements.
- to rotate the whole mechanism to get the tilt orientation needed.
Frankly, I hardly can imagine this to happen (robustness).
And the user interface dealing with at least three independent focus points seems a challenge for me as well. (This is to be done by the body, not the lens)
The first is whether Canon will implement this patent, e.g. because it wouldn't be robust enough. If I had to bet $10, I would be on your side.
The second is, if Canon implements this patent, how much power it would consume.
