I don't have a depth of field calculator handy but I'm guessing that at F4 and focused to infinity you are not going to have something 4feet away in focus at a 29mm focal length . You ought to check it out.

Yes I agree and wasn't expecting the foreground to be in focus, main concern for me was the top right corner which looks like mush and is kilometers into the distance same for the upper left side which looks soft also.

Ok, do see what you mean in far corners.  There could be some field curvature.  Strongly advise f/8.
