Correct, the LCD isn't flush totally. I think it's a little thicker because of the touch capability. If you turn it around it should look more flush, so that's normal.
The shutter is definitely louder, but more...robust sounding, for lack of a better word. Apparently the 7DII is much quieter, surprisingly so. Lens shouldn't have anything to do with the shutter sound.
Thanks hokiealumnus. It sits fine towards hinge side. It doesn't sit properly towards end side.
