The only question is lens coverage but then it is only a problem for shift, not for tilt...
So what do you think? Should we ask this next?

This would transform a great camera into a legendary camera :D

Speaking of shift, there's something Pentax could do to crush forever all competition :
- Sensor shift for architectural photography
- Sensor tilt for increased depth of field or funny effects

Honestly, as they already have 5 axis sensor moves, horizon ajustements and so on, this would be the logical move to make. It wouldn't take much on the sensor level to get the moves needed for some good Scheimpflug effects, to cross the floor plane...

And now Pentax could compete with my Toyo field :)
