The maximum value for auto ISO sensitivity
can be selected using

(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 modes P and A , sensitivity will only be adjusted if
underexposure would result at the shutter speed selected for
Minimum
shutter speed
(
1
/
4000
–1 s, or
Auto
; in modes S and M , ISO sensitivity will be
adjusted for optimal exposure at the shutter speed selected by the user). If
Auto
(available only with CPU lenses; equivalent to
1
/

s when a non-CPU lens
is used) is selected, the camera will choose the minimum shutter speed based
on the focal length of the lens (auto shutter-speed selection can be fine-tuned
by highlighting
Auto
and pressing
2
; for example, even faster values than
those usually selected automatically by the camera can be used with telephoto
lenses to reduce blur). Shutter speeds slower than the minimum value may be
used if optimum exposure can not be achieved at the ISO sensitivity value
selected for
Maximum sensitivity
. Press
J
to exit when settings are complete.
