The camera is maintaining a usable exposure setting in order to get proper images to display on the EVF or LCD.

It's part and parcel of the mirrorless experience. Exposure control is no longer a "when the shutter is released" kind of thing -- it's continuous whenever the viewfinder is active. There's nothing you can do about it.

When you half-press, the camera will adjust to your shooting parameters, which means it'll stop down to your designated aperture and will stay there until the picture is taken or you release the shutter button.

Hi Doug, your explanation is correct, but still it remains a bit strange on why they do that: the fact that the lcd/evf can show a properly metered/exposed image when you half press the shutter (and hence close the aperture to your setting in Aperture Prio mode) means that they can somehow adapt the evf/lcd readout to show a well exposed image with any aperture.

It would be impossible for carefully conceived and executed experiments to have produced these results. I suggest that you undertake to meticulously document a series of experiments crafted to convince skeptics like me that your observations are correct. Along the way, you will likely discover where your thinking is wrong.
