A pro using a camera and a pro camera doesn't mean the same thing.
Some Pros use iphones. It means nothing. A pro camera is, btw, mostly used by amateurs full of money

Originally posted by monochrome Logic then says there won't be a FF camera mirrorless camera. Since Pentax has repeatedly said 1) they are developing a FF camera, 2) there is room for a third full-line camera company and it will be Pentax, 3) they are committed to the three existing mounts, then logically they are developing a FF K-mount dSLR. A 4th mount with a FF adapter seems unlikely.
None of which has anything to do with the K-S1.
You forgot the part where they stated that, in their view, APS was the max size for a mirrorless camera (couple years ago, so to be placed in the context).

Originally posted by THoog In addition, most of the KAF pins are there to communicate the smallest and largest apertures of the lens (NOT the current aperture setting, mind you- just the largest and smallest it is capable of). A mechanical linkage opens and closes the aperture, based on how far the camera thinks it should move the arm. That's a 1980s way of doing things - most new mounts communicate digitally between the camera and lens, and the lens does the work. So do you force the new A mount to still use an 'old' linkage method, or do you put the servo motor and mechanical bits in the adapter? Do you keep the screwdrive motor in the camera body, or put that in the adapter, too? (Sony did just that for the non-motored-lens-Alpha-to-E-mount adapter.)
You actually described KA mount. Later revisions have the digital pin which solves that (KAF).
This does not contradict what you wrote but I doubt most of the other contacts are necessary for KAF compatibility. KA for sure though.
