Hyperfocal Calc calculates the Hyperfocal distance for a given combination of focal length and aperture of the camera lens. The hyper focal distance for a lens zoomed to a particular focal length is defined as the nearest distance of focus which maximizes the depth of field. In other words, when the camera is focused at the hyper focal distance for the given aperture-focal length combination, everything from half distance as the hyper focus distance to infinity will be recorded sharp in the photograph. It features nearly 2400 popular still cameras in its database, automatically saves user settings, you can start right where you left, calculations for user chosen focus distance, US customary units and metric units, and it also calculates near focus distance, far focus distance and depth of field.
