Depth of Field Calculator
Calculate depth of field, hyperfocal distance, and focus range for photography
About this calculator
A depth of field calculator is an essential tool for photographers to determine the range of distance that appears acceptably sharp in their images. This calculator computes depth of field, hyperfocal distance, and focus range based on your camera settings including focal length, aperture, and focus distance. Understanding these measurements helps photographers achieve precise focus control for portraits, landscapes, macro photography, and other creative applications where depth of field management is crucial for professional results.
How to use
Enter your camera's focal length, selected aperture (f-stop), focus distance, and sensor size into the calculator. The tool will instantly compute your depth of field range, showing the near and far focus limits, plus the hyperfocal distance for maximum sharpness throughout your scene.
Frequently asked questions
What is hyperfocal distance in photography?
Hyperfocal distance is the closest focusing distance where objects at infinity appear acceptably sharp. Focusing at this distance maximizes depth of field from half the hyperfocal distance to infinity.
How does aperture affect depth of field?
Smaller apertures (higher f-numbers like f/11) create greater depth of field with more area in focus, while larger apertures (lower f-numbers like f/2.8) create shallow depth of field.
Does sensor size impact depth of field calculations?
Yes, larger sensors produce shallower depth of field at equivalent focal lengths and apertures. Full-frame sensors have different depth of field characteristics compared to crop sensors or smartphones.
