<em><strong>Correction:</strong> I said this patent was from 2010, when it is in fact from July of 2017.</em></p>
<p>Keith over at Northlight uncovered a patent application from <del>2010</del> July, 2017 that shows a tilt-shift lens with both autofocus and image stabilization.</p>
<p><strong>Patent Summary:</strong></p>
<blockquote><p>Whilst it is a form of AF, it’s actually mentioned in the patent for correction of tilt angle. The lens also has sensors to feed back tilt and shift details for the camera to decide how to manage all this stuff.  Conventional AF is also a feature (it’s a patent application so can have all kinds of whistles and bells included). <em><a href="http://www.northlight-images.co.uk/canon-ef-lenses-rumours-and-news/">Read more at Northlight</a></em></p>

<p>Keith also <a href="http://www.northlight-images.co.uk/using-lens-tilt-on-your-digital-slr/">wrote an article as to why focus affects tilt</a>, which helps explain why we don’t have autofocus tilt-shift lenses currently.</p>

The picture shows a mirror and a pentraprism, but theoretically if they build this lens for a mirrorless system (EF mount or a new mount), it won't require any special crazy stuff, because the AFing will be straight forward at the sensor.

I would not expect that patent to be realized any time soon. When developing the latest set of TS-E lenses Canon apparently thought about adding this stuff but did not do it (either too many technical compromises or too expensive).
If it really comes (some time after everybody bought the currently new TS-E lenses) it will likely cost around 5000€.
