Get hyperfocal distance and the near/far limits of acceptable sharpness for any focal length, aperture, sensor size and focus distance. Perfect for landscape work.
| Aperture | Hyperfocal | Near limit | Far limit | Total DOF |
|---|
Hyperfocal H = f² / (N × c) + f, where f = focal length, N = aperture, c = circle of confusion. Near limit = (H × s) / (H + (s − f)). Far limit = (H × s) / (H − (s − f)); negative means infinity.
Focus at the hyperfocal distance for maximum DOF: everything from H/2 to infinity is acceptably sharp.
