Cameras recommendations

I decided to get the Pentax K1 camera for these reasons:

  1. It has image stabilization on the sensor.
  2. No Anti Aliasing filter.
  3. Super resolution by sensor shift.

I know there are some recommendations to not use lenses with built in stabilization.
What about image stabilization in the sensor like the one on Pentax K1 ? Will it affect the reconstruction ? Or the guidance refers only to lenses with built in stabilization ?

Do you think that the Super resolution by sensor shift from K1 can help the reconstruction or it should be turned off ?

While searching for a wide angle prime lens for Pentax k1 I noticed that many have only manual focus.
Do you think it will be hard to keep the objects in focus without an autofocus lens ?

Thank you !
