So, here's a question about these multipoint autofocus systems. How does one change the focus point? I'd imagine that it's a time consuming operation, pushing buttons or turning wheels or some such electro-mechanical modal interface <LOL>. Seems then that for scenes where there's any quickness of action required on the part of the photographer, adjusting autofocus preferences might be a hindrance, and that using just one focus point and slightly shifting the camera may be a faster alternative. But, if one does that, as noted by Vic, how does that effect the point of focus? Is it changed because the camera has moved? And, can one focus with autofocus on an area where there's no contrast or even a subject? For example, if one wanted to use a hyperfocal distance and, at that point there's nothing to focus on? Or if one wanted to focus on a mono-colored wall for instance? Which brings up another question: if newer lenses have no DOF scale (I understand that some don't), how can one use the hyperfocal focusing technique?
