ok, it's hard to explain everything especially if I don't want to complicate this. I hope this helps, you can also use Google to search interesting sites (a lot) about this, for example:

1. Exposure Value (EV) compensation

autoexposure


EV -2.0
use negative EV if you want to reduce overexposure (too bright)


EV +2.0
use positive EV if you want to reduce underexposure (too dark)


of course you have to know that this isn't magic solution which will make wonders. it can help only if overexposure/underexposure problem is not too big


2. AutoExposure (AE) lock
use half pressed shutter key (this one which you're using to focus and taking pictures) to lock AE. it will be locked just before autofocusing process. with locked AE you can point your camera everywhere and exposure will be 'freezed'. release shutter key and you will unlock AE

AE locked (overexposure)
exposure locked at dark object and then camera pointed at bright object (screen)


AE locked (underexposure)
exposure locked at bright object (screen) and then camera pointed at dark object


how to use it? move your camera to find good exposure for your scene (e.g. well balanced sky and ground brightness for landscape). lock AE and now you can move your camera more to sky or to ground without any problems with brightness

AE is locked not before as I wrote earlier but after focus, when box is green. changes during focusing like small zoom in/out is because of lens is moving, it's normal. I can't answer on rest of your question because I don't have described by you effect on my K800. one more thing, pay attention on AE lock used with focus infinity - is it working in K850? I'm asking because it's not working in K800 (this bug was never fixed)
