Frequently Asked Questions

Why does a wide angle lens have a much shorter hyperfocal distance?

Because hyperfocal distance scales with the square of focal length (H ∝ f²). A 24mm lens at f/8 has a hyperfocal distance of only ~7.9 feet (sharp from 4 ft to infinity), whereas a 50mm lens at f/8 requires 34 feet.

What happens if I focus directly at infinity instead of the hyperfocal distance?

If you focus at infinity, infinity is sharp, but your near depth-of-field limit only reaches back to H (wasting half of your potential foreground sharpness window).

What is the standard Circle of Confusion for full frame cameras?

The historical standard circle of confusion for 35mm full frame film and sensors is 0.030 mm (or 0.025 mm for high-resolution 45+ megapixel sensors viewed at 100% crop).

How does sensor crop factor affect hyperfocal distance?

Smaller sensors require higher enlargement to reach standard viewing sizes, requiring a smaller circle of confusion (e.g. 0.020mm for APS-C vs 0.030mm for Full Frame). However, achieving the same field of view requires a shorter focal length lens, which dramatically shortens the hyperfocal distance.
