This may be old news to most users of this camera and its siblings but I was curious. All these observations were done with "Quality" set to raw only. This is, of course, a mirrorless camera. I don't have access to any other brand so perhaps others will say if theirs behave differently.

● When shooting M with "auto ISO" the EC changes the ISO.
● When shooting M with fixed ISO the EC not only doesn't do anything, the camera tells me it won't do it.
● When shooting Shutter priority and fixed ISO, EC changes the aperture.
● When shooting Shutter priority and auto ISO, EC tries to apply the change to aperture but if pressed will also change ISO. In my simple tests using my monitor as a target, it wanted to use ISO 200 until it couldn't.
● When shooting Aperture priority and fixed ISO EC changes the shutter speed.
● When shooting Aperture priority and auto ISO EC tries to apply the change to shutter but if pressed will also change ISO. In my simple tests using my monitor as a target, it wanted to use ISO 200 until it couldn't.
● When shooting "P" and fixed ISO EC changes both the aperture and shutter speed but I'm not sure how it decides what to change and how much (unless, of course, it hits the limit of the aperture).
● When shooting "Intelligent Auto" the camera won't accept exposure compensation and tells me that.

When the camera accepts the exposure compensation it also shows a brightness change in the rear screen and also in the VF. In other words, the camera will either accept the EC and show the result visually or it will indicate that it refuses.

All of this seems logical and expected but with some settings it's not - at least for me - crystal clear what will happen when it can change two variables. When it can only change one then it's very predictable.

I shoot a Sony A7RIII and except for the last statement, that's what my camera will do. The A7RIII doesn't have "Intelligent Auto". Manual mode with fixed ISO won't allow EC on almost any body because you have full control of the exposure. When you set Aperture Priority & Auto ISO, the meter will adjust the shutter speed until it reaches a predetermined limit & will then adjust the ISO. You might consider purchasing Gary Friedman's book on the a6500 body. It will answer a lot of questions & probably some situations you haven't thought of yet.

All that is verrrry typical of modern cameras.

A brand to brand variance is whether or not the EC setting biases the manual metering scale. Some do, some dont.

In my Nikon cameras while in full manual mode EC changes what the camera meter reports as correct exposure to allow you to manually adjust your settings to zero out the meter to include the EC selected.

That’s pretty much how it works on every camera I’ve used. I pretty much stick to modes with only one variable setting, so i only use auto ISO with “M”. If you really want too shoot with auto ISO in other modes and you want to know what’s going to happen when you use EC then you should experiment and note at which point it stops adjusting the expected setting and starts adjusting ISO.
