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.

So why they constantly change it when you do not half press the shutter and point the camera to brighter/darker areas is still a mystery to me. It is actually quite annoying as it makes a rattling sound in e.g. the kitlens.

So if you have any thoughts on that, please share as i also like to know how this stuff works inside.
