"The hyperfocal distance..."

...is the distance to which you focus your lens manually to get maximum depth of field that extends to infinity. The image will be sharply focused (to a resolution defined by the "circle of confusion") from 1/2 the hyperfocal distance to infinity. Hyperfocal focusing is most often used in landscapes. The circle of confusion I chose for the D100 corresponds to two pixel elements in the final image at highest resolution--that is, acceptable focus is defined as a point being focused to no more than two pixels wide on the D100, which should be perceived as quite sharp in the final image. If you want the ultimate in sharpness, double the hyperfocal distances to focus a single point on a single D100 pixel element. Can't get any sharper than that with a digital sensor.

Hope that helps.

Cheers.
