Taking Photographs—Sensitivity (ISO Equivalency)

Sensitivity (ISO Equivalency)

Reacting Faster to Light

“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 100 and ISO 800 in steps equivalent to 1/3 EV. Settings of HI-1and HI-2(respectively 1 EV and 2 EV over ISO 800) are available where high sensitivity is a priority. Sensitivity can be adjusted using the ISO option in the shooting menu or by pressing the ISO button and rotating the main command dial.

1 Highlight ISO in the shooting menu ( 166) and press the multi selector to the right.

2 Highlight the desired option and press the multi selector to the right. The shooting menu will be displayed.
