A Auto ISO sensitivity control when taking photos
If you set [ISO sensitivit
y settings] (0245) > [Auto ISO sensitivity control]
in the photo shooting menu to [On], the camera will automatically change
the ISO sensitivity when proper exposure cannot be obtained with the ISO
sensitivity set in modes P, S, A, and M.

ou can adjust the ISO sensitivity only under the following settings. In
all other cases, the camera automatically adjusts ISO sensitivity.
- Mode: M
- [ISO sensitivity settings] > [Auto ISO control (mode M)] in the
video recording menu: [O]
･ Choose from values of from ISO 100 to 25600. If the ISO sensitivity
dial is set to any other value, it will be set to ISO 25600.
D High ISO sensitivities
The higher the ISO sensitivity, the less light needed to make an exposure,
allo
wing pictures to be taken when lighting is poor and helping prevent blur
when the subject is in motion. Note, however, that the higher the sensitivity,
the more likely the image is to be aected by “noise” in the form of
randomly-spaced bright pixels, fog, or lines.
D H1 and H2
A setting of [H1] (H
i 1) corresponds to an ISO sensitivity approximately 1 EV
higher than ISO 51200 (equivalent to ISO 102400) and [H2] (Hi 2) to an ISO
sensitivity approximately 2 EV higher (equivalent to ISO 204800). Note that
pictures taken at these settings are particularly prone to “noise” in the form
of randomly-spaced bright pixels, fog, or lines.
