ISO speed guide
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.
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.
Note
Can also be set on the [ ISO speed ] screen in [ : ISO speed settings ].
To add [ H ] (equivalent to ISO 51200) as an available option, set [ ISO expansion ]
to [ 1:Enable ] in [ : Custom Functions(C.Fn) ] ( ).
Caution
Setting [ : Highlight tone priority ] to [ Enable ] or [ Enhanced ] will prevent you
from selecting ISO 100/125/160 or [ H ] (equivalent to ISO 51200) ( ).
Shooting in high temperatures may result in images that look grainier. Long
exposures may also cause irregular colors in the image.
When you shoot at high ISO speeds, noise (such as dots of light and banding) may
become noticeable.
If you use a high ISO speed and flash to shoot a close subject, overexposure may
result.
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.
As “
H ” (equivalent to ISO 51200) is an expanded ISO speed setting, noise (dots of
light, banding, etc.) and irregular colors will be more noticeable, and the resolution
will be lower compared to the standard setting.
