Sensitivity (ISO Equivalency)

Reacting Faster to Light

Taking Photographs

“Sensitivity” is the digital equivalent of film speed. The higher the sensitivity, the less light needed to make an exposure, allowing higher shutter speeds

or smaller apertures.

Sensitivity can be set between values roughly equivalent to ISO 200 and ISO 1600 in steps equivalent to 1/3 EV. Sensitivity can be adjusted using the ISO option in the shooting menu or by pressing the ISO button and rotating the main command dial.

Sensitivity

The higher the sensitivity, the more likely pictures are to be subject to “noise” in the form of randomly-spaced, brightly-colored pixels.
