If the sensor can't communicate with the lens, how is it is supposed to know when a subject is in focus? For the same reason AF doesn't work I would not expect the camera to know it is in focus with a non native lens. However if you say Pentax has pulled this off then cool beans. My A7R works the same as the Fuji.

Hi Chad

Yes that's how it works.  I often use the Tamron SP 300/2.8 at sporting events focused  on a part of the track and then raised a tad so that the image is out of focus at the focus point. When the Car / bike (whatever) comes into focus the shutter fires.

Saves a lot of wasted shots!
