ISO Sensitivity

The camera's sensitivity to light (ISO sensitivity) can be adjusted in response to lighting conditions. In general, the higher the ISO sensitivity, the less light needed to make an exposure, allowing faster shutter speeds or smaller apertures. The options available vary with the shooting mode.

High ISO sensitivity, fast shutter speed (ISO 3200, 1/125 s)
Low ISO sensitivity, slow shutter speed (ISO 200, 1/5 s)

Shutter speeds drop when ISO sensitivity is low, which can produce blurring in photographs taken indoors or under low light.

High ISO sensitivity (ISO 12800)
High ISO sensitivity (ISO 6400)

High ISO sensitivities of ISO 6400 to 12800 may also be necessary for concert photos taken in small venues or to freeze motion in sports shots.

SLR cameras produce good results even at high ISO sensitivities, so don’t be afraid to adjust ISO sensitivity as the situation requires.


ISO sensitivity can be adjusted by pressing the ISO button and rotating the main command dial until the desired setting is displayed in the control panel and viewfinder.
ISO sensitivity can also be adjusted using the ISO sensitivity settings option in the photo shooting menu.
