What is the hyperfocal distance at 10mm f/8 on APS-C?

At 10mm, f/8, on APS-C (1.5x-labeled Nikon/Sony/Fujifilm format), the hyperfocal distance is roughly 0.68 meters (2.2 feet) — close enough that focusing there puts virtually the entire scene in front of the camera, from about 0.34 meters onward, in acceptably sharp focus.

Ultra-Wide Territory on a Crop Sensor

10mm is a common wide-zoom starting point on APS-C, reading as roughly a 15mm-equivalent field of view — genuinely dramatic wide-angle territory. At this short a real focal length, the hyperfocal distance collapses to well under a meter even at a moderate f/8, which is exactly why real estate and interior photographers working at this focal length rarely need to think hard about focus placement for front-to-back sharpness.

What Changes This Number

Stopping down to f/11 shortens it further, to roughly 0.49 meters, though at this point the practical benefit is marginal — the sharp range already extends from close to the lens to infinity at f/8. Opening up to f/5.6 lengthens the hyperfocal distance somewhat, which matters more for a wide-aperture interior shot than for typical landscape use.

This is one of the shortest hyperfocal distances anywhere on this site's APS-C reference, a direct result of squaring an already-short 10mm real focal length in the hyperfocal formula — the f² term shrinks fast enough at this end of the wide-angle range that aperture choice barely matters compared to what it does at a longer focal length.

Frequently Asked Questions

Do I even need to think about hyperfocal focusing at 10mm?

Less than at any longer focal length — the hyperfocal distance is already under a meter at a moderate aperture, so as long as you're not focusing extremely close to the lens, front-to-back sharpness is close to automatic at this focal length.

What field of view does 10mm give on APS-C?

Roughly a 15mm-equivalent field of view — a genuinely dramatic ultra-wide angle, common as the wide end of APS-C ultra-wide zoom lenses used for interiors, architecture and expansive landscapes.
