Hyperfocal Distance Tablev1.0.0

Generate a hyperfocal distance lookup table for a chosen camera sensor across multiple focal lengths and apertures. 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. Maximize sharpness across landscape, street, and architectural scenes without performing calculations in the field.

• Select the Camera Sensor / Film Format from the dropdown. The sensor size determines the circle of confusion (CoC) used in every calculation. For unlisted sensors, choose Custom Circle of Confusion and enter the value in millimeters.
• Choose a Distance Unit (feet, meters, inches, or centimeters). All hyperfocal distances display in this unit.
• Enter Focal Lengths as a comma-separated list in millimeters. Each focal length becomes a column. Common values are pre-filled. Add or remove any value, and use fractions, mixed numbers, decimals, or scientific notation as needed.
• Tick or clear Apertures to Include. Each selected f-stop becomes a row. Standard full-stop values from f/1.4 through f/32 are available.
• Click Generate Table or wait for the auto-update. The table displays the hyperfocal distance for every combination of selected focal lengths and apertures.
• Open Settings to switch between displaying the hyperfocal distance alone or with the near limit (half the hyperfocal distance), adjust decimal precision, and optionally display the formula derivation.
• All settings persist locally and via URL query parameters, so a configuration can be shared by copying the page URL.

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.

Hyperfocal distance tables serve photographers, cinematographers, educators, and optical engineers who need reliable focus zone references. A printed or bookmarked 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, look up the hyperfocal distance for a 24mm lens at f/11 and set focus to that distance to keep everything from foreground wildflowers to distant mountains acceptably sharp.
• Street Photography: Pre-focus a 35mm lens at its hyperfocal distance for f/8 so that subjects from roughly 8 feet to infinity remain 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. Students observe that 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.
