I am not so sure about this. Thee are a lot of issues with camera functionality for non conducting mounts that were introduced with the K7. Before this, for example you could stop down manual lenses (I.e. Non a lenses) for metering etc. this whole functionality was changed with the K7 it is not just catch in focus.
I do not know what drove this change in total.
It is like the change in exposure compensation. The *istD for example had EV comp in manual, so you could make a correction for a lens, or for a deliberate shooting condition even if you were in manual, but with the K10 and later, this was no linger possible..
