Depth of field calculator

Near/far focus limits, total depth, and hyperfocal distance from focal length, aperture, and subject distance.

Depth of field from focal length, aperture, and focus distance — with the hyperfocal distance that maximizes the sharp zone.

Circle of confusion: full frame 0.029 mm, APS-C 0.019, M43 0.015, 1-inch 0.011. Runs in this browser.

How to use

  1. Enter focal length and aperture.
  2. Enter subject distance and pick a circle of confusion (sensor).
  3. Read near/far limits, total DoF, and hyperfocal distance.

What it supports

Thin-lens approximation; CoC presets for full-frame (0.029 mm), APS-C (0.019), Micro Four Thirds (0.015), and 1-inch (0.011) sensors. Beyond the hyperfocal limit the far bound reads ∞. Macro distances are not modeled.
