The first translation of the easy of hyperfocal distance or distance Hiperfokal are: the distance from the lens into a point of focus where the focus point to infinity (infinity) is sharp. Coupled with a bonus: half of the distance from that point towards a sharp lens also (acceptable sharpness).
Why do I call a bonus? Because we really put the focus point of camera / lens distance hiperfocal us at that point was to get the field DOF (depth of field) broadest sense from the point / distance to the Infiniti but krg over half the distance from that point forward (toward) the lens also participate significantly in limits acceptable sharpness (acuity that can still be accepted.)
From the first illustration image below, If we do peeked from the viewfinder and put the focus point at point A, then from point A until the Infiniti will enter in the field of DOF (depth of field) or often called a sharp field. But we also mendaptakan bonus acuity that is half the distance from point A to the lens also sharp. Or in other words, from point B to the Infiniti will be sharp.
The second translation of the hyperfocal distance is: the distance from the lens to the point that from that point forward would be sharp if the lens difocuskan at the point of infinity. In other words from that point until the Infiniti will be sharp.
