Diffraction at f/14#
Diffraction softening becomes visible at 100% once the Airy disk spans more than about two pixels. It is a gradual effect, not a cliff.

f/14 on smaller sensors equals…#
Exposure (brightness) is the same at a given f-number on every format; equivalence describes depth of field and total light.
| Used on | Full-frame equivalent depth of field |
|---|---|
| APS-C (1.5×) | f/21.0 |
| Canon APS-C (1.6×) | f/22.4 |
| Micro Four Thirds (2×) | f/28.0 |
| 1-inch (2.7×) | f/37.8 |

When to use f/14#
f/14 is a go-to setting for maximum depth of field (macro, focus-free landscapes) and long exposures in daylight, at the cost of diffraction softness.

Frequently asked questions#
Is f/14 a wide aperture?
No — f/14 is a small (narrow) aperture. Smaller numbers mean larger openings.
How much light does f/14 let in compared to f/2.8?
0.04× (-4.6 stops).
