Automatically set within ISO 100 - ISO 6400
P / Tv / Av / M Automatically set within ISO 100 - ISO 16000
B ISO400
With flash ISO400 (except in the <> mode)
  • The actual ISO speed range depends on the [Minimum] and [Maximum] settings set in [Auto ISO range].
  • Reduce the ISO speed if fill flash causes overexposure. The minimum is ISO 100 (except in the <M> and <B> modes). 
  • In the <P> mode, ISO 400 - ISO 1600 is automatically set if the external Speedlite is set for bounce flash.
 

Manual modes

Set the ISO speed adjust light sensitivity to suit the current light level.

    • High ISO speeds can result in grain.
     
    ISO speed Shooting situation (No flash) Flash range
    ISO 100 - ISO 400 Sunny outdoors The higher the ISO speed, the farther the flash range will be.
    ISO 400 - ISO 1600 Overcast skies or evening time
    ISO 1600 - ISO 16000, H1, H2 Dark indoors or night

 

Good to know

  • As H1 (equivalent to ISO 25600) and H2 (equivalent to ISO 51200) are expanded ISO speed settings, noise (dots of light, banding, etc.) and irregular colors will be more noticeable, and the resolution lower than usual.
  • If [ : Highlight tone priority] is set to [Enable], ISO 100/125/160, H1 (equivalent to ISO 25600), and H2 (equivalent to ISO 51200) cannot be selected.
  • If you set H2 (equivalent to ISO 51200) and shoot a movie, the camera will switch to H1 (equivalent to ISO 25600) with manual-exposure movie shooting. Even if you switch back to still photo shooting, the ISO speed will not revert to H2.
  • Under [ : ISO speed setting increments] is set to [1-stop], you can still select ISO 16000.

Shooting guidelines
  • Shooting in high temperatures or at high ISO speeds may result in images that look grainier and include dots of light and banding.
  • Long exposures can also cause irregular colors in the image.
  • 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.
  • If you use a high ISO speed and flash to shoot a close subject, overexposure may result.
