Option Description
[ISO sensitivity]
View the ISO sensitivity selected with the ISO sensitivity dial.
When the dial is rotated to C
, this option can also be used to adjust
ISO sensitivity. Choose from settings of ISO100 to 64000, settings below
ISO100 by about 0.3, 0.7, and 1EV (ISO 50 equivalent), and settings above
ISO 64000 by about 0.3, 0.5, 1, and 1.7EV (ISO 204800 equivalent). An
[Auto] option is available in b mode.
[Auto ISO
sensitivity control]
Select [ON] to enable auto ISO sensitivity control. If [OFF] is selected, ISO
sensitivity will remain fixed at the value selected with the ISO sensitivity
dial. [Maximum sensitivity], [Maximum sensitivity with c], and [Minimum
shutter speed] options are available when [ON] is selected.
[Maximum
sensitivity]
Choose an upper limit for ISO sensitivity to prevent it being raised too high.
[Maximum
sensitivity with c]
Choose the upper ISO sensitivity limit for photos taken using an optional
flash unit.
[Minimum shutt
er
speed]
Choose the shutter speed below which aut
o ISO sensitivity control will kick
in to prevent under
exposure in modes P and A; options range from ¹⁄₄₀₀₀
to 30s. If [Auto] is selected, the camera will choose the minimum shutter
speed based on lens focal length. For example, the camera will automatically
choose faster minimum shutter speeds to prevent blur caused by camera
shake when a long lens is attached.
To view auto shutter-speed selection options, highlight [Auto] and press
2. Auto shutter-speed selection can be fine-tuned by choosing faster
or slower minimums. Faster settings can be used to reduce blur when
photographing fast-moving subjects.
Shutter speeds may drop below the selected minimum if optimal
exposure cannot be achieved at the ISO sensitivity chosen for [Maximum
sensitivity].
