Using ISO Sensitivity ISO Sensitivity is a measure of how the camera's sensor reacts to light. Setting a high ISO will let you take pictures with smaller apertures under low lighting conditions or make it easier to freeze action with faster shutter speeds. However, the higher the ISO, the more likely "noise" in the form of randomlyspaced, brightly-colored pixels may appear. ISO Sensitivity can be selected in M and E modes.
