Hyperfocal Distance Chart
What is "Hyperfocal Distance"?
Very briefly, when a camera lens is focussed at the "hyperfocal distance" everything in the photograph from some object close to the camera to objects far away (we say, at infinity) will be sharp. Being able to focus your lens properly is therefore an important requirement if you want to have objects in a particular range all pin sharp in the final image.
A very good review of hyperfocal distance is available at Dofmaster, [this link opens in a new window] where you will also be able to download free software to produce various hyperfocal distance charts for any lenses you use on your camera.
An example hyperfocal distance chart for full-sensor slr cameras is available HERE.
