What would cause the camera to go out of focus in such a way that the center of the image is blurred, but near the edges the image is sharp??

Can you post a sample.

Only faulty optics may produce such thing.

It would be best if you posted an image, it's more than likely a fault with the camera. Is the blurriness permanent, or does it come and go ?
