p.1 #1 · p.1 #1 · Questions about Nikon AF


How do I set each person in a group to stay in AF? With one person I can use the dial and move the square box around to there face so the AF stays great. But with like two or more people some times the AF don't light up on there face. So is there a way to set each face in the view finder with the dial on the right of the lcd?

Well if the subjects in a group are all in the same plane, parallel to the film plane, they should be all in focus even if only one face is "found"...if they're in different planes, then you just have to stop down, because the AF itself cant focus on two things at once that are at different distances....or you buy a tilt shift lens and manually focus...

As Nathan is eluding to you need to learn more about aspect of "depth of field". You can only focus on one point at a time with "any" camera and lens. What ends up being suitably "in" focus depends on the aperture chosen and the focal length of the lens used. So, the smaller the f/stop and typically the more wide the lens is the more things in the images will be in focus.
