[QUOTE="aroy, post: 526239, member: 16090"] Here is how you can check the AF accuracy. Use these camera settings . ISO 100 (not Auto) . Mode "A" . Aperture Wide open, For kit lens use 55mm at F5.6 . AF Area Mode - Single point . Focus Mode - AFS . Metering - Matrix . Select Centre AF point . If you have a garden or a back yard, mount the camera on a tripod and point it to a fence or a chair or a table. If you do not have a tripod, set the camera on a stable surface - flat table or a chair . If using a fence set the camera at an oblique angle and focus using half press at an edge. . Once satisfied with the focus press the button fully. . If you want to negate camera shake, use burst mode to shoot 6 or 8 frames in a burst. Now check the images in your computer. If the camera if functioning properly then the edge you aimed at should be in focus. If the sharp focus is away from the edge you aimed at, then the AF is off.
