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).

Frequently asked questions#
Is ISO 102,400 high?
Yes, it is a high ISO. Emergency territory: expect heavy noise and colour shifts; use for documentation or creative grain.
When should I use ISO 102,400?
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.
