EOS R7 Auto ISO goes to highest setting and stays there

[Deneye]

When I set the ISO on my R7 to auto it goes to the highest ISO setting and stays there. Does anyone have an idea of how to deal with this? Thanks!

Doesn't it change the ISO value when you start metering and aim the camera at a bright scene? Take a picture outside and look at the ISO value stored in the picture file. It should vary based on the scene brightness and other settings (aperture, shutter speed).

I don't have a R7 but you should be able to set a range of low to high limits for Auto ISO. I know some cameras show the high ISO setting when you set Auto ISO. They have to show something. You might try a camera reset if all else fails.

I would like like to have the camera adjust to changing light. Maybe I’ll try a reset see if that works

thanks!

 I have changed the ISO and it still just goes as high as I have set. I really like auto ISO when tracking wildlife or when I want to quickly take a photo and at least be close to correct exposure

I would also suggest resetting the camera back to its factory defaults.  What is your setting on th shooting mode dial on the top of the camera?

Some combinations and shooting conditions can yield unexpected results.  One common rabbit hole is allowing the camera to control more than one leg of the Exposure Triangle at the same time.  I would only use ISO Auto when the shooting mode is set to M.  

Using ISO in Av or Tv modes can yield unexpected results and the right conditions.  This is why the camera has a menu setting called “Safety Shift”.  This setting when combined with others are intended to limit unexpected or erroneous automatic exposure settings.  I disable them.

Try this after you do a camera reset.  Before you start changing camera settings, set the shooting mode to the Green [A+] mode.  Do the camera exposure and ISO values seem reasonable?  If so, then that would suggest that you had a perfect storm of camera settings and shooting conditions to create the high ISO settings when using ISO Auto.

What those settings were does not matter.  Just observe the basic rule of thumb of not allowing the camera to control more than one leg of the exposure triangle at a time.  When using Tv or Av mode, you should dial in an ISO value, as well as disable “Safety Shift”, which is how it was named in DSLRs.  I can find it in the first Orange Camera menu in the R6, and it uses the same name.

I only use manual.

Reset worked! Now I will customize my buttons and see how it goes
