Focus+ 1.65

Focus+ is a versatile photographic depth of field calculator. Given the focal length of a lens and desired circle of confusion it can accurately calculate the hyperfocal distance, front/back or near/far depth of field, and optimum focus distance and aperture. The results are tabulated by aperture to aid fast look-up in the field and to see the results in context. Display can be switched between full, half and third stops.
