I am reading about this AF-confirm chip here:
http://www.16-9.net/nikon_g/
This makes me wondering and curious... I always thought that it's the camera itself that determines when something is in focus. The camera controls the focussing of the lens and when camera thinks that focus point has been reached, it will stop telling the lens to focus. But apparently that's wrong thinking, is it really so that the lens is telling the camera when the object is in focus? Also what's the point of having such an AF-confirm chip inside an adapter if the camera can't auto-focus the lens anyway (because for example it's a Nikon lens on a Panasonic cam).
I hope my questions make sense. And I'm just trying to understand how auto-focussing actually works, even though I prefer manual focussing most of the time now.
