E ISO Sensitivity
Sensitivity is a measure of how quickly the camera reacts to light. The higher the
sensitivity, the less light needed to make an exposure. Although a high ISO rating
is suited for shooting subjects in action or in poor lighting, high sensitivity is often
associated with "noise" - randomly spaced, brightly colored pixels concentrated in
dark parts of the image.
Auto (default setting)
Sensitivity is ISO 80 under normal conditions; when lighting is poor and the flash is
off, the camera compensates by raising sensitivity to a maximum of ISO 800 (note
that ISO sensitivity is fixed at 80 in M mode).
80, 100, 200, 400, 800, 1600, 2000
Sensitivity will be locked at the specified value.
At the settings other than Auto, the current setting is displayed (A 6). If Auto is
selected and the sensitivity is raised above ISO 80, the E icon will be displayed
(A 29).
