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 Hi 1 and Hi 2
A setting of [H
i 1] corresponds to an ISO sensitivity approximately 1 EV
higher than ISO 51200 (equivalent to ISO 102400) and [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.
Auto ISO sensitivity control
Auto ISO sensitivity control automatically adjusts ISO sensitivity if
optimal e
xposure cannot be achieved at the value selected by the user
in modes P, S, A, and M. You can select an upper limit for auto ISO
sensitivity control (200–Hi 2) to prevent ISO sensitivity being raised too
high.
･ Hold the
S
button and rotate the sub-command dial to select from
ISO AUTO (auto ISO sensitivity control enabled) and ISO (auto ISO
sensitivity control disabled).
