Depth-of-Field Calculator - NS 2.0 MSIE 3.0 or later Required

To find the near, far and hyperfocal distance for a specific lens, enter the focal length (mm), aperature (f/number) and the object distance (whole or decimal number). The JavaScript program will calculate the near, far, depth and hyperfocal distances. The unit of measure for distances is feet. This can be overridden by selecting meters. Your MSIE browser will print these tables, others must print screen to the clipboard and then print from some other application.

Depth-of-Field - Unit of Measure is meters.
