Hyperfocal Distance Calculator
The hyperfocal distance is the focus point that squeezes the maximum possible depth of field from a lens: focus there and everything from half that distance all the way to infinity stays acceptably sharp. This is the single most useful trick in landscape photography, where you want the foreground rock and the distant mountain both crisp. Enter your focal length, aperture, and sensor size, and this calculator returns the hyperfocal distance plus the near edge of the sharp zone once you focus at that point. Stopping down the aperture or using a wider lens pulls the hyperfocal distance closer, giving more front to back sharpness. The formula uses the circle of confusion matched to your sensor format so the result reflects real acceptable sharpness. All calculation happens in your browser with nothing sent to a server.
How to use Hyperfocal Distance Calculator
- Enter your focal length.
- Enter the aperture as an f-number.
- Select your sensor size.
- Read the hyperfocal distance to focus at.
- Note that sharpness then runs from half that distance to infinity.
Frequently asked questions
What is hyperfocal distance?
It is the focus distance that keeps everything from half that distance out to infinity acceptably sharp, maximizing depth of field for a given focal length and aperture.
How is it calculated?
It uses focal length squared divided by the product of aperture and the circle of confusion, plus the focal length, with the circle of confusion set by sensor size.
Why is it useful for landscapes?
Focusing at the hyperfocal distance gives the deepest possible sharpness for a scene, which is why landscape photographers use it to keep foreground and background sharp.
