Originally posted by em-tx I am coming from point that all FF lenses can be adopted on MILC.
Hm, what do you mean? All K-mount FF lenses can already be mounted on K-mount camera. The reason many MILC allow adapted lenses from different
systems (not just APSC vs. FF) is because of their short register distance. This is why Pentax can be mounted on Canon camera, but not the other way around (both same register distance, but Canon mount is bigger in diameter), and this is why Pentax lenses can be mounted on Q, but not the other way around (Q lens would have to be inside the camera, where the mirror is). If the register distance is wrong, then the lens will not be able to focus properly.

The latest thread about these lenses:

There are links posted inside the first thread (post by cali92rs). The second thread shows the concept with old third party lens (posted by me, scroll down).
Originally posted by em-tx For a MILC, probably there would need to be a new mount,
Ah, and here is the problem. You already have Q, (micro) four thirds, Olympus, Fuji, the Sony mounts, Samsung, Panasonic.. there are plenty. Does Pentax really need to join? And throw away its main advantage - K-mount?
If Pentax makes a K-02, there is a good chance I would try to get one. But if its not K-mount? Meh, doubt it.
