Estimate hyperfocal distance and near/far depth of field limits with documented assumptions. Choose from sensor presets or enter a custom circle of confusion value.
Hyperfocal distance uses H = (f² / (N · CoC)) + f. Distances are rounded to two decimals. Far limit is infinity when focus distance exceeds hyperfocal distance.
Scenario: Landscape with 24mm lens on full frame camera
Settings: f/8 aperture, focus at 3 meters
Hyperfocal distance: ~1.8m at f/8
Depth of field: Everything from ~1.2m to infinity appears sharp
Tip: Focus at hyperfocal distance for maximum sharpness from half that distance to infinity
The maximum blur diameter (in mm) that still appears sharp to the human eye. Smaller sensors need smaller CoC values.
The closest focus distance where the far limit of depth of field reaches infinity. Focus here for maximum sharpness from foreground to background.
When you focus at or beyond hyperfocal distance, everything from the near limit to infinity appears acceptably sharp.
Choose based on your camera: full frame (35mm), APS-C (crop sensor), Micro 4/3, or medium format. Check your camera manual for crop factor.
Very accurate for the given CoC value, but real-world sharpness depends on lens quality, diffraction, and viewing conditions.
