I agree with everything you said. But sadly, I think zone focusing is almost a lost art.

It's a funny thing to say even if its kind of true. I don't think there's much difference between back button focus and zone focusing really though. In both cases, you're pre-focusing the camera, it's just the method of moving the lens and the time between set and click that differs.

Regardless how you focus though, I think it only makes sense that the lens should stay focused where you left it, until you choose to change it.

One of the problems with today's AF lenses is they are all focus-by-wire with no hard stops at minimum focus and infinity. With every manual lens I have that's 23mm or wider, I carefully focused the lens in on a target 10 feet away and marked that focus point on the focus ring. Using a DOF calculator, I also know what f-stop I have to be at to get a DOF large enough to have everything from five feet to infinity in focus. So, all I have to do is align the mark on the aperture ring and the focus point mark on the lens barrel, stop down to the right aperture or beyond, and my focus is set unless I move the focus ring or I want or need a shallower DOF.
