Same noise on other formats#
At the same framing and depth of field, a full-frame camera at this ISO produces similar noise to the smaller formats at the lower ISOs shown (equivalence theory).
| Full frame ISO 2,000 ≈ on | Equivalent ISO (same total light) |
|---|---|
| APS-C (1.5×) | ISO 889 |
| Micro Four Thirds (2×) | ISO 500 |
| 1-inch (2.7×) | ISO 274 |
| Medium format 44×33 (0.79×) | ISO 3,205 |

Frequently asked questions#
Is ISO 2,000 high?
Moderate. Fine on APS-C and full frame; visible noise in shadows on small sensors.
When should I use ISO 2,000?
When you need the shutter speed and aperture shown in the table above for your light level. Raise ISO only after you've reached the slowest safe shutter speed and widest useful aperture.
