I believe so, if I understand your question. When you're looking through the EVF, and you have live preview enabled (the alternative being that the camera just shows you a nice, bright image no matter how badly you've screwed up the settings), then:
1. The image you see in the EVF adjusts as you adjust the settings - brighter, darker, in / out of focus, and depth of field will all appear in the viewfinder as they will appear in the finished image
2. If you want them, the camera will also display the ISO, shutter speed, and aperture. If you have one / all of those on Auto, then there's nothing to display until you half-press the shutter, but once you do, everything locks in place and the settings you're about to expose with are displayed.
You can turn any or all of those off on either the EVF or the LCD, as well as many more options, including:
- electronic level
- focus distance with DOF scale overlaid on it
- remaining shots at current size on memory card
- jpg film simulation profile (velvia, astia, etc)
- image quality level
- EV scale, with "normal" (17 grey) in the center, and tick marks every 1/3 stop in both directions, so if you are in full manual, it will show you with a small yellow mark if you're over or under exposing according to the camera's meter mode... just the camera's 2 cents
