🆅 Depth of Field Calculator
Calculate the zone of sharpness for your camera, lens, and focus distance.

| Canon EOS 90D, Rebel series | APS-C Canon | 1.6× | 0.019 |
| Sony A6000/A6600, Nikon D500, Fujifilm X-T4 | APS-C Nikon/Sony | 1.5× | 0.020 |
| Olympus OM-D, Panasonic GH5/GH6, Lumix G9 | Micro Four Thirds | 2.0× | 0.015 |
| Sony RX100, Canon G7X, DJI drones | 1-inch | 2.7× | 0.011 |
How Depth of Field Works
Depth of field (DOF) is the range of distance in a scene that appears acceptably sharp in a photograph. Objects closer or farther than this zone will appear progressively blurred.
Circle of Confusion (CoC) is the largest blur spot the eye can perceive as a point at normal viewing distance (a print viewed at ~25cm). This is sensor-size dependent.
Hyperfocal distance is the closest focus distance at which objects at infinity are still acceptably sharp. Focusing at the hyperfocal distance maximizes the DOF from half that distance to infinity — critical for landscape photography.
To get shallower DOF (portrait bokeh): use a wider aperture (lower f-number), longer focal length, or move closer to your subject. To get deeper DOF (landscape sharpness): use a narrower aperture, shorter focal length, or focus at the hyperfocal distance.
