[QUOTE="Marcel, post: 386381, member: 3903"] My opinion is that before you try to blame the lens or camera, you have to do some test for focus. Put the camera on a tripod and find yourself a non moving subject with good light. Use 1 point focus in the center in AF-S mode, take a few shots of the same subject but in between shots turn the camera to do the focus on another plane. This is done to see if the camera will focus back on the same way. Then, using LiveView and the magnifier while in manual focus, make the focus as sharp as you can and take a picture of the same subject. Then go over to your computer, make a few 100% crops of the auto-focus shots and compare them with the LiveView manual focus. This will: 1- Confirm if the camera is front-back focusing and if the focusing is consistent. 2- Will let you send Nikon service center a proof of the malfunction is there is one. If you don't want to go to all that trouble, then just try using AF-S single point to acquire focus and then recompose and shoot. This is what I do and find the most efficient for me. Good luck.
