    Setting the ISO Speed (EOS 7D Mark II)

    18-Sep-2014
    8202163300

    Solution

    Set the ISO speed (image sensor’s sensitivity to light) to suit the ambient light level.
    In <> mode, the ISO speed is set automatically.

    Setting the ISO Speed
    1. Set the camera's power switch to <ON>.



    2. Set the Mode Dial to < P / Tv / Av / M / B>.



    3. Press the < ・ISO> button.



    4. While looking at the LCD panel or the viewfinder, turn the <> dial to set the ISO speed.


    NOTE
    • ISO speed can be set within ISO 100 – 16000 in 1/3-stop increments.
    • "A" indicates Auto ISO. The ISO speed will be set automatically
    ISO speedShooting Situation
    (No flash)    		Flash Range
    ISO 100 - ISO 400Sunny outdoorsThe higher the ISO speed, the farther the flash range will be.
    ISO 400 - ISO 1600Overcast skies or evening time
    ISO 1600 - ISO 16000, H1, H2Dark indoors or night
    *High ISO speeds will result in grainier images.

    IMPORTANT
    • 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.
    • Shooting in high temperatures may result in images that look grainier. Long exposures can 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.
    • 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.
    • If you set H2 (equivalent to ISO 51200) and shoot a movie, it 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.
    REFERENCE
    • Under [ : ISO speed settings], you can use [ISO speed range] to expand the settable ISO speed range up to H2 (equivalent to ISO 51200)
    • Even if [ : ISO speed setting increments] is set to [1-stop], you can still select ISO 16000.

    Auto ISO



    If the ISO speed is set to "A" (Auto), the actual ISO speed to be set will be displayed when you press the shutter button halfway.
    As indicated below, the ISO speed will be set automatically to suit the shooting mode.
    Shooting Mode ISO Speed Setting
    Automatically set within ISO 100 - ISO 6400
    P / Tv / Av / M Automatically set within ISO 100 - ISO 16000*1
    B ISO400*1
    With flash ISO400*1*2*3*4

    *1: The actual ISO speed range depends on the [Minimum] and [Maximum] settings set in [Auto ISO range].
    *2: If fill flash will cause overexposure, ISO speed may be reduced, down to a possible minimum of ISO 100 (except in the <M> and <B> modes).
    *3: Except in the <> mode.
    *4: In the <P> mode, if the external Speedlite is set for bounce flash, ISO 400 - ISO 1600 will be set automatically.
