ISO speed guide

Low ISO speeds reduce image noise but may increase the risk of camera shake and subject blur or reduce the area in focus (shallower depth of field), in some shooting conditions.
High ISO speeds enable low-light shooting and a larger area in focus (deeper depth of field) but may increase image noise.

Note

To extend the maximum manual ISO speed setting to H (equivalent to ISO 102400), adjust [ISO speed range] in [: ISO speed settings] ().

Caution

Image noise (dots of light or banding) and irregular colors may increase and apparent resolution may decrease at H (equivalent to ISO 102400), because this is an expanded ISO speed.
Image noise (such as graininess, dots of light, or banding), irregular colors, or color shift may be noticeable at high ISO speeds, in high temperatures, or with long exposures.
Normal image recording may not be possible under conditions that cause excessive noise, such as a combination of high ISO speed, high temperature, and long exposure.
For precautions on high ISO speed, see General Movie Recording Precautions.
