I agree with 4wd and others that the most visible defect is probably the shimmering pattern, called moire, due to the pattern of the distant grape vines. Is that what you mean by fuzziness? If so, there is not much to be done about it, except to clean it up in post. A pro would mask out the affected areas and selectively blur them or use other tricks (fft filtering) to minimize the moire. Sharpening will make it worse, and blurring will degrade the overall image.
