Terragon DOF Calculator

With the DOF Calculator, you can calculate the depth around the focus-point, where the Object will still be sharp.

Lens focal length in mm:
F-number :
Focus distance in meters:
Circle of confusion in mm (check your sensor here):

Depth for acceptable sharpness : 800.8 mm / 2.63 feet / 0.8 meters
Near distance for acceptable sharpness : 4631.4 mm / 15.2 feet / 4.6 meters
Far distance for acceptable sharpness : 5432.3 mm / 17.8 feet / 5.4 meters

Hyperfocal distance* : 61676.4 mm / 202.4 feet / 61.7 meters

*Wikipedia July 2015: In optics and photography, hyperfocal distance is a distance beyond which all objects can be brought into an acceptable focus. When the lens is focused at this distance, all objects at distances from half of the hyperfocal distance out to infinity will be acceptably sharp.
