Universal Depth Of Field Tables

The universal depth of field tables permit you to figure out your depth of field for virtually any lens at any distance, from three feet to 400 feet. Although most lenses have depth-of-field scales marked on the mounts, they are not really precise enough.

To use this table, first determine the hyperfocal distance for the lens you are using from Table 1 (the green Table). The hyperfocal distance is the zone of sharpness when your lens is set for infinity (). It extends from infinity towards your camera. the shorter the focal length and the smaller your lens aperture (f/number), the greater the hyperfocal distance. This is indicated by the zone of sharpness moving closer to your camera.

Then take the nearest value of the hyperfocal distance and check the depth of field using Table 2 (the red Table) to find your zone of sharpness at the distance setting of your lens.

For example, if you are using a standard 50 mm (2-inch) lens on your 35 mm camera and the f/stop is 11, your hyperfocal distance is 15 (feet). On the depth of field chart, the nearest value is 15. If your camera is focused for 10 feet, your depth of field will extend from 6-0 (6 feet 0 inches) to 30 feet. If your camera is focused for 20 feet, your depth of field will extend from 8-7 (8 feet 7 inches) to infinity ().

To convert measurements from feet and/or inches to metres, just multiply the amount of feet by 0.3048 and inches by 0.0254. So 8 feet 7 inches are (8 * 0.3048)+(7 * 0.0254) = 2.616 metres.

Standard of sharpness: circle of confusion = 1/1000 of the focal length. For a circle of confusion 1/1500 of the focal length or for a 1½ x long focus or telephoto lens used with the same camera multiply the hyperfocal distance by 1½; for 1/2000 of the focal length or a 2 x long focus or telephoto lens multiply by 2 and so on.
