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.

Caution

  • 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.
