Who wants a pentax with Tilt-Shift Sensor?

I really would like if Pentax would work on such a feature.

What would be different from the composition adjustment feature?

We already have some shift: https://www.pentaxforums.com/forums/115-pentax-k-5/222795-sensor-shift-2.html#post2973944

It can do pretty well for what's basically a 'freebie' feature piggybacking on the SR.

Tilt would be nice but I expect outside the scope of the current SR system.

hardware thing, so maximum quality and no pixel stretching.
although will turn every lense into tilt-shift - more working possibilities with DoF. would be a hell of work, rotating the camera, trying to catch the right angle. but imagine that you can maximize your DoF with any macro lens.

How could a lens be focused on a tilted sensor? Lenses focus to a specific distance on a plane perpendicular to the axis of the lens.

Shift exists already and its good. Pentax is using the SR pretty well. It gives us Shake Reduction, AA filter, Shift adjustment, Astrotracing.. One more thing they could do is add SR-shift bracketing, to create higher resolution files. Adding tilt to the SR would be much more difficult, though. It would be a technological marvel, so I am all for it, but I won't hold my breath waiting

It would be no different from a tilt-lens. You end up tilting the plane of focus to line up with something that isn't perpendicular to the lens axis. Here's a good rundown: Using Tilt-Shift Lenses to Control Depth of Field

No, because the viewfinder would be different, unless it would tilt along with the sensor. It is important which part tilts, if its the lens, then everything from there on will see things tilted - AF module (not that tilt lenses have AF), metering, EVF, OVF. If its just the sensor, it would have to be done in live view. And probably without AF.

It could be made to work in my the same way as the rear movements on a view camera. That being said, maximum utility would be had by mating such a sensor with a tilt/shift lens.

The difference is subtle, but there is a difference. It is the physical position of the front lens element relative to the subject that drives perspective. Most view cameras allow front swing/tilt/rise/shift while the same movements at the rear are not as common.

only if your subject is on a single plane perpendicular to the axis of the lens. every object in front of a lens is in focus at some point in three dimensional space behind the lens, simultaneously.

IMHO, a better solution would be to use one of the available view camera modifications that allow mounting a dSLR body in place of ground glass/film at the rear standard.

Pentax composition adjustment is a "hardware thing". No stretched pixels.

Yes of course- same reason the SR shift is only available in live view mode. This part should be obvious:P. I was mostly responding to how the plane of focus tilts, and in no way meant to imply that a tilting sensor and a tilting lens would be identical in use.

Seems like contrast-detect AF would still work though.

Sure, 'similar idea' would have been a better phrasing on my part. You could tilt your entire non-tilting lens and camera combo and then use sensor tilt to un-tilt your sensor to get the same effect as a not-tilting your non-tilting sensor but tilting the tilt lens in front of it. Or something like that?

I think simply buying a tilt shift lens would be easier
You have some options, Schneider, Arax, Samyang, and then there are the tilt adapters, too..

An slr mirror box reduces the utility of such a sensor, as does lens coverage. A TS lens is a better solution.

Simple...just put said APS-C sensor in a 645Z body!
