user is higher than that chosen for Maximum sensitivity, the
value selected by the user will be used instead). In exposure
modes P and A, sensitivity will only be adjusted if

Minimum shutter speed (

exposure at the shutter speed selected by the user). If Auto is
selected, the camera will choose the minimum shutter speed
based on the focal length of the lens. Press J to exit when
