Here are some thoughts about hypothetical K-mount adapters for use with hypothetical Pentax mirrorless new-mount cameras.

How comprehensive could a K-mount adapter be?

Could it control the aperture lever? Could it drive screw-focus lenses?

Is this a rhetorical question? We know it can be done, because it was done before - see Sony's LA-EA4. Actually the Sony does more, as it includes a PDAF system.

Would Pentax supply a K-mount adapter?

Another rhetorical question. Yes, they would. The only question is the level of support.

What do adapters bring to the party?

A Pentax new-mount camera with an adapter attached is equivalent to a new K-mount camera. Pentaxians are encouraged by new K-mount cameras!

I disagree with this - a very important difference would be the impossibility of having an optical TTL viewfinder.

An adapter is just a means to facilitate migration to another mount. It is needed only for those who decided to migrate, and completely useless to the others.

And in practical terms, it is a myth that there have to be new lenses on day 1. The camera could be attractive enough in its own right, especially if it were bundled with an adapter.

An interchangeable lens camera with no lenses makes no sense. OTOH they could get away with just 2-3 lenses for the beginning.
