What is this tool?
Estimates depth of field from focal length, aperture, subject distance, and sensor size (shared crop-factor / circle-of-confusion presets). Shows near and far limits plus how much of the DOF sits in front of versus behind the focus point. Based on standard thin-lens formulas — real optics vary.
How to use it
- Enter focal length (mm), aperture (f-number), and subject distance.
- Choose a sensor size / crop-factor preset.
- Read near limit, far limit, and front/behind DOF.
