ISO Speed Settings
ISO Speed Guide
z
Low ISO speeds reduce image noise but may increase the risk of
camera/subject shake or reduce the area in focus (shallower depth of
field), in some shooting conditions.
z
High ISO speeds enable low-light shooting, a larger area in focus (deeper
depth of field), and longer flash range but may increase image noise.
z
Can also be set in [ISO speed] in [
z
ISO speed settings] .
z
Under [
5
: Custom Functions(C.Fn)] , if [ISO expansion] is set to [1:On] , “H”
(equivalent to ISO 51200) can also be selected (
=
461).
z
Image noise (such as dots of light or banding) may increase and apparent
resolution may decrease at H (equivalent to ISO 51200), because this is an
expanded ISO speed.
z
If
[

is set to
[Enable]
or
[Enhanced]
( = 144),
ISO 100/125/160 and H (equivalent to ISO 51200) cannot be selected.
z
When shooting with a high ISO speed, high temperature, or long exposure,
image noise (rough grain, dots of light, banding, etc.), irregular colors, or color
shift may become noticeable.
z
When shooting in conditions that produce an extreme amount of noise, such as
a combination of high ISO speed, high temperature, and long exposure, images
may not be recorded properly.
z
If you use a high ISO speed and flash to shoot a close subject, overexposure
may result.
