Hyperfocal Distance Calculator
Calculate hyperfocal distance to maximize depth of field. When focused at hyperfocal distance, everything from half that distance to infinity will be acceptably sharp—perfect for landscape photography.
Default: 0.03mm for full-frame
How to Use This Calculator
- Enter your lens focal length in millimeters.
- Enter your aperture setting (f-stop number).
- Adjust the circle of confusion if using a non-full-frame sensor (default 0.03mm works for full-frame).
- The calculator displays hyperfocal distance and the depth of field range (near limit to infinity).
- Focus your lens at the calculated hyperfocal distance for maximum depth of field.
Hyperfocal Distance Formula
Hyperfocal distance is calculated using focal length, aperture, and circle of confusion:
Example: A 24mm lens at f/11 with 0.03mm CoC: Hyperfocal = (24²) ÷ (11 × 0.03) = 576 ÷ 0.33 = 1,745mm = 1.75m. Focus at 1.75m, and everything from 0.875m to infinity will be sharp.
Full Description
Hyperfocal distance is one of the most powerful techniques in landscape photography. It allows you to maximize depth of field, ensuring that both foreground and background elements are sharp. Instead of focusing at infinity (which wastes near-field sharpness) or using guesswork, hyperfocal distance gives you the exact focus point for optimal results.
When you focus at hyperfocal distance, the depth of field extends from half that distance to infinity. This means if your hyperfocal distance is 2 meters, everything from 1 meter to infinity will be acceptably sharp. This is perfect for landscape photography where you want maximum sharpness throughout the frame.
The calculation depends on three factors: focal length (shorter = closer hyperfocal), aperture (narrower = closer hyperfocal), and circle of confusion (sensor-dependent). Use this calculator before shooting to determine the optimal focus point, then use your lens\'s distance scale or manual focus to set it precisely. Many landscape photographers carry hyperfocal distance charts or use apps, but this calculator provides instant, accurate results for any combination of settings.
Frequently Asked Questions
What is hyperfocal distance?
Hyperfocal distance is the focus distance that maximizes depth of field. When focused at hyperfocal distance, everything from half that distance to infinity will be acceptably sharp. This is essential for landscape photography where you want maximum sharpness.
How do I use hyperfocal distance in practice?
Set your lens to the calculated hyperfocal distance (use manual focus and distance scale if available). Everything from half that distance to infinity will be in focus. This eliminates the need to focus at infinity and waste near-field sharpness.
Does hyperfocal distance change with aperture?
Yes! Wider apertures (lower f-numbers) increase hyperfocal distance, while narrower apertures (higher f-numbers) decrease it. This is why landscape photographers often use f/8 to f/16 for maximum depth of field.
What is circle of confusion?
Circle of confusion (CoC) is the maximum size a point of light can appear on the sensor while still being considered "in focus." It varies by sensor size: full-frame uses 0.03mm, APS-C uses 0.02mm, Micro Four Thirds uses 0.015mm. Smaller sensors need smaller CoC values.
