Setting camera for Zone Focus What is the easiest way to set a camera up for Zone Focus? I use the D-200 and D-70.

Robert, If we are talking about the same definition, I see no problem here. Zone focus (to me) is simply pre-focusing on a predetermined point. If that is what you are asking, I can't see why this is a problem?

Yes Pete, I was reading through a wedding photography book and they were giving the example of shooting on a dance floor during the reception. You set your camera to focus on anything within a set range and just shoot away. Anything outside of that range would be out of focus. Of course you would have to turn off the auto-focus to make this happen. My thinking is what happens if you see something outside that range. I have to wear glasses to look at the controls of my camera to make adjustments, but while shooting I don't need them. Maybe I'm making something big out of something small.

Robert Using my D80 in AF-S ( this is an auto mode) I only have to press the shutter button halfway to lock the focus,and after taking the shot keeping the shutter pressedhalfway-anything in the room will be in focus as long as it's the same distance as the original shot. in AF-A and AF-C modes (still auto focus) I have to use the lock button (not the shutter release button)

I think I see what you want to do. Since you know how to pre-focus; you are asking how to determine what is in and out of focus? That is a depth of field question and dependent of the f/stop chosen. Most of todays lenses no longer use a DOF scale..bummer. There is a lot of talk about calculating "hyper-focal" distance on this board. If you do a search for those terms, you will see how it is done without a DOF scale. Personally, I see little need or use for being able to calculate it, as we live in the digital world...(i.e) Instant image feedback. Obviously, if you zoom in for a tight shot, the DOF is reduced. With time and years of practice, I have essentially learned my DOF with various f/stops and focal lengths. This is easily practiced. In other words, with experience, you will simply know if you focus on your subject that at f/8 with a 50mm lens, all is in focus X amount in front of your subject and X amount beyond. Calculating "Hyperfocal" distance will tell you exactly how much fore and aft. Hope that helps a little, all the best, Pete
