Sensitivity is a measure of how quickly the camera reacts to light. The higher the
sensitivity, the less light needed to make an exposure. Much as film with a high
ISO rating tends to produce “grainy” images, high sensitivities may however be
associated with “noise”—randomly-spaced, brightly-colored pixels concen-
trated in dark parts of the image. Choose from values between ISO 64 and ISO
3,200.
Auto is equivalent to ISO 64 under normal conditions; when lighting is
poor and the flash is off, the camera compensates by raising ISO sensitivity to a
maximum of ISO 800 (note that ISO sensitivity is fixed at 64 in mode
M ).
The current ISO sensitivity is displayed in the monitor at settings other than
Auto ( B 4). If Auto is selected, an
ISO
icon will be displayed when sensitivity is
raised above ISO 64.

Image sizes over 2,592×1,944 (

) are not available at ISO 3200 ( B 66). If 3,648×2,736 (

3,648×2,432 (

), or 3,584×2,016 (

) is selected for Image size when ISO sensitivity is set
to 3200, Image size will automatically be set to 2,592×1,944 (
f
). The original image size
will be restored when a lower ISO sensitivity is selected.
When 3200 is selected for ISO sensitivity, image size is displayed in red and the slowest
shutter speed available is 2s.
