Hyperfocal Distance Table

A hyperfocal distance lookup table covers a chosen camera sensor across multiple focal lengths and apertures at once. The hyperfocal distance is the closest focus point at which a lens can be set so that everything from half that distance to infinity falls within acceptable depth of field, which is what makes maximum sharpness in landscape, street, and architectural scenes possible without calculating anything in the field.

• Sensor and film format presets set the circle of confusion (CoC) used in every calculation; a custom circle of confusion in millimeters covers any unlisted sensor.
• A distance unit, feet, meters, inches, or centimeters, applies to every hyperfocal distance shown.
• Focal lengths are entered as a comma-separated list in millimeters, and each becomes a column; common values are pre-filled, and fractions, mixed numbers, decimals, or scientific notation are all accepted.
• Each selected f-stop becomes a row; standard full-stop values from f/1.4 through f/32 are available.
• Settings switch the table between the hyperfocal distance alone or paired with the near limit (half the hyperfocal distance), adjust decimal precision, and optionally display the formula derivation.

The hyperfocal distance formula is H = f² / (N × CoC) + f, where f is focal length in millimeters, N is the f-number, and CoC is the circle of confusion. When focused at H, depth of field extends from H/2 to infinity.

A 24mm lens at f/11 with a typical full-frame CoC of 0.03mm gives H = 24² / (11 × 0.03) + 24 = 576 / 0.33 + 24 = 1769.45mm, about 1.8 meters. That is the table entry a landscape photographer would look up before focusing: setting the lens to roughly 1.8 meters puts the near limit at H/2, about 0.9 meters, with everything from there to infinity rendered acceptably sharp.

Hyperfocal distance tables serve photographers, cinematographers, educators, and optical engineers who need reliable focus zone references. A printed or saved table eliminates mental math in the field and supports consistent maximum-sharpness results.

• Landscape Photography: Print the table for the most-used lenses and tape it inside the camera bag. At a scenic overlook, looking up the hyperfocal distance for a 24mm lens at f/11 and setting focus to that distance keeps everything from foreground wildflowers to distant mountains acceptably sharp.
• Street Photography: Pre-focusing a 35mm lens at its hyperfocal distance for f/8 keeps subjects from roughly 8 feet to infinity in focus. Zone focusing allows shooting without autofocus and never missing a candid moment.
• Astrophotography: Determine the hyperfocal distance for a wide-angle lens at its widest aperture. When shooting the Milky Way, focusing at or slightly beyond the hyperfocal distance keeps both stars and foreground terrain inside the depth of field.
• Architectural Photography: Compare hyperfocal distances across tilt-shift focal lengths (17mm, 24mm, 45mm) to plan which combination keeps an entire building facade sharp from near corners to far edges without extreme apertures that introduce diffraction.
• Education: Demonstrate how hyperfocal distance changes with focal length and aperture. Shorter focal lengths and smaller apertures produce shorter hyperfocal distances and greater overall depth of field.
• Videography: Calculate hyperfocal distances for cinema lenses at common T-stops. For walk-and-talk scenes or documentary footage, focusing at the hyperfocal distance provides a reliable zone of sharpness without constant focus pulling.
• Lens Comparison: Generate tables for several focal lengths to evaluate which lens delivers the best near-to-infinity sharpness at a preferred working aperture, useful when choosing primes for a travel kit.
