thanks Mako. I appreciate your help. In all pictures I focused on the area by the maroon bush by the building and thought I had focus lock. I will try again.

According to ViewNX2 and other EXIF viewers, focus was never locked in any of the pics. Check the AF/M switch on both lens and camera body. Cycle them to AF. Makes sure the lens is mounted properly, clicks in place, and the lens release button is not stuck...redo testing again. Good luck.

Mako, where do you see that focus was never locked in the viewers. I don't see that information when I look at the EXIF. Where do I look?

Simplest way..use viewNX2 and click on the "focus Point" box at the top right area so it turns yellow. If focus was locked and the green light was lit in the viewfinder at the time of capture...you will see a red box on the image showing what AF sensor was active. If no red box...no green light or lock.

I retested and did get the green dot indicating focus was locked. I did as you suggested above and retested again at f8. The center is okay but the rest of the image is a mess still, especially on the left. I am getting rather frustrated.

Do you now get a red box in viewNX2 with the new pic? Have you tried with another lens? Do you get a red box with that lens? Me thinks there may be a lens contact issue. Defocus the lens so it is completely blurry (by turning the focus ring)...when you try to auto focus..does it move?

I appreciate your help. Thanks again.
