High-Sensitivity Movie Mode
Movies shot at high sensitivities are prone to noise (randomly-spaced
bright pixels, fog, or lines) and after-images of light sources and other
bright objects. If the subject is brightly lit, highlights may be “washed
out” and details may be lost. Check the results in the monitor and turn
high-sensitivity movie mode off if necessary. Note that the camera may
have difficulty focusing using contrast-detect autofocus.
Although m is displayed whenever high-sensitivity mode is enabled,
photographs taken while high-sensitivity movie mode is in effect are
shot at the ISO sensitivity selected for ISO sensitivity in the shooting
menu (
0 110).
