This version includes the reverse DOF feature.

Contrary to the classical depth-of-field calculation, the reverse DOF feature allows you to calculate the focus distance and moreover the minimal aperture , given the lens focal and the near and far limit of sharpness.

Upgrading PocketDOF from version 1.0 to version 1.1 is free.
