i have seen first hand that it is indeed quite true. Acoarst certain UHH Experts will insist otherwise, cuz its really only conditionally true.
The applicable conditions have already been posted over and over again, but all mixed in with factoids such as what you apparently believe.

Rubbish.

Don't let the ISO change in M mode when you make an EC change and you'll see that the meter does change. Can you do that and then understand what's happening? Or is that too difficult?

No, not for me. But I'm not the one that said that was the only thing that happened with EC change. Two reasons for EC, not just one. But I'm not the one that said "Period".

I don’t get it! If you use EC in Manual what if anything would it do? You told it to set the aperture, the shutter speed and ISO. If you want say +1 EC wouldn’t it be just as easy to adjust one of the three plus one stop?
It might bias the exposure measurement regardless of other settings. That is risky because if accidentally set all exposures could be incorrect until you discover the problem.
Likewise auto ISO in Manual doesn’t make any sense.

I disagree with your statement that “Auto ISO in Manual doesn’t make any sense.” Think of it as just another semi auto mode like Aperture Priority or Shutter Priority where you set two of the exposure parameters and the camera sets the remaining parameter. One genre in which using auto ISO in Manual mode is helpful is street photography. Often the photographer will want to lock in a higher shutter speed (to freeze motion of folks walking within the scene) and an aperture based on desired depth of field (particularly critical when opting to use zone focusing) - allowing the camera to float the ISO to balance out the lighting is handy here. You could, of course, vary the ISO manually but that can become burdensome in changing conditions and when you are trying to pay attention to events occurring in real time.

No one said that. Here's the post you first responded to: https://www.uglyhedgehog.com/t-762756-9.html#13681513 Maybe if you read it?

I can understand that what you just said above is false.
Your response to Larry is wrong. Claiming you're right by saying someone said something they didn't is a poor argument.

Period.
Strike out Period. Make it Exclamation mark!
Like a lot of technology it does what you tell it nothing more, nothing less.

EC does not change the meter indication in Auto ISO. Period.
Larry is wrong. You are wrong.

There is an exposure mode on most cameras called Manual Mode. It does not specify what ISO should be set.
You cannot change the definition of these terms to suit your whims.

It matters not that M is selected. It is no longer manual if you select auto ISO. Why is “auto” so difficult to understand? Manual means that you set the three parameters each to a fixed value and reset them as necessary.

Maybe pictures will help. Below are two photos of the back LCD of a Nikon Z7. I have labeled them A and B.
Note the mode indicator circled in red is M for Manual, (ISO is set auto).
Note that the meter is zeroed in both.
(The scene is under unchanging indoor lights at night. The camera is tripod mounted and not moved in any way.)
Note the exposure parameters for photo A are 1/40 sec, f/5.6 and ISO 3200. The meter is zeroed in photo A for those parameters and that scene.
Note in photo B the symbol that indicates an EC change is labeled and circled in red. That means an EC change has been made.
Note the exposure parameters for photo B are 1/40 sec, f/5.6 and ISO 2200. The meter is zeroed in photo B for those parameters and that scene.
The scene has not changed and is identical in both cases. Yet in photo B the meter is zeroed for a different set of exposure parameters than in photo A. Therefore the meter indication has changed. In Photo B the meter is indicating different exposure parameters than it did for photo A.
The EC change caused the meter in Photo B to indicate a different set of exposure parameters. And that's the meter indication changing. You are wrong.

Your two photos plainly show the METER reading does NOT change.
The metering scale runs vertically on the right edge. The shutter and aperture numbers do not constitute a metering scale. The vertical scale ALWAYS tells us about image brightness. The numbers at bottom do NOT. Brightness IS exposure.

First, there is no such thing as a "meter indicator" on the Nikon display. Read the manual.
There is a "metering" indicator on the lower left; it shows "center weighted metering" in both images. Not changed.
There is an "exposure indicator" on the lower right; it shows that the image is at "optimal exposure" at the current settings.
There is an "exposure compensation icon" displayed in the second image, that indicates a non-zero value for exposure compensation.
What this does show, is that the ISO has changed and the exposure indicator has not changed.
You and Larry keep saying falsehoods about EC, and your own example proves it.

But Larry doesn't use auto ISO when he in manual mode.
