| This may apply to all DSLRS...ok, so I when you want to change the focus point you use the little pad to change where the box is in the view finder. My question is, can you make it so that it focus on more than one area, or in a circular area not just that one point, so that if I take a picture of a persons face while they are looking at me from an angle I can get both the eyes in focus rather than just the one I have the box centered on? |

The focus point (that you can move around) is just showing what "plane" will be in focus. If you focus on one eye, and the other eye is on the same plane (the same distance and angle from the camera), it will be in focus too. |

OK, I understand that.
I may be way off base here, but isn't there a way to set your camera so that it focuses on a larger area. On the LCD display on the top of the camera it shows where it focuses. Is there a setting so that instead of focusing on just a plane like that, it focuses on different distances? So if my subject is on an angle, not facing me, but in the middle of the frame, I can get both eyes in focus even though one eye is further away from the camera?
I'm using a face as an example, but this can be a building or any other larger object as well. I just thought that there was somewhere where I can make the camera focus on multiple points, or in a circular etc type way. |

You're talking about depth of field, and the only way to change it is by changing your aperture. There's nothing "in camera" that can alter how much of your scene is in focus.
For the face, the best thing you can do is focus between the eyes. Or, use a smaller aperture.

He's talking about depth of field AND area focus AND confusing the two. |

| The only way to change your plane of focus is to get one of THESE. |

I know Canon bodies have an "A-DEP" (automatic depth of field) mode which uses multiple focus points to automatically pick an aperture for the DOF needed/wanted, I've never used it though. Not sure if Nikon has this too. There's no other way to change the amount of a scene that is in focus.

Yes, Nikon has it, too. I don't really know how it works, though - I keep using the single point.
I'm kinda hoping someone who knows how to use the other focus settings will post! I mean, on the D200 there are FOUR options for autofocus, and Nikon's marketing gibberish is essentially useless for deciphering them.
