3 Adjust settings.
The maximum value for auto
ISO sensitivity can be selected
using Maximum sensitivity
(the minimum value for auto
ISO sensitivity is automatically
set to ISO 100; note that if the ISO sensitivity selected by the
user is higher than that chosen for Maximum sensitivity, the
value selected by the user will be used instead).
In exposure
modes e and g, sensitivity will only be adjusted if
underexposure would result at the shutter speed selected for
Minimum shutter speed (
1
/4000–30 s, or Auto; in modes f and
h, ISO sensitivity will be adjusted for optimal 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 settings are
complete.
When On is selected, the viewfinder and
rear control panel show Z.
When
sensitivity is altered from the value selected
by the user, these indicators flash and the
altered value is shown in the viewfinder and rear control panel.
A Minimum Shutter Speed
Auto shutter-speed selection can be fine-tuned by highlighting Auto
and pressing 2: for example, values faster than those usually selected
automatically can be used with telephoto lenses to reduce blur.
Note,
however, that Auto is available only with CPU lenses or when lens data
are provided for non-CPU lenses; if a non-CPU lens is used without lens
data, minimum shutter speed is fixed at
1
/30 s.
Shutter speeds may drop
below the selected minimum if optimum exposure can not be achieved
at the ISO sensitivity chosen for Maximum sensitivity.
