I've had the 24-85mm f3.5-4.5 non VR for sometime and I always had a problem with it. First on the D300 and now on the D800. The problem is that the center is not at all sharp but the corners are OK.
The lens is not expensive but I just wanted it to be OK, so I took it in to have the lens re-calibrated. The Slovenian Nikon dealer instead of doing what I wanted did an auto focus adjustment and charged me 50 euros. The lens is no better than how it was. I told them that the D300 and D800 have the AF Fine Tune and therefore there was no point doing what they did.
I was then offered an optical re-alignment in Germany. The lens was sent and now Nikon Germany says that the lens is within factory specification. The lens will now be sent back.
So, what exactly is "Within factory specification"? And more importantly, do you think that there is a problem with my lens, or am I just being difficult?

yes, like joachim said, it looks like misfocus. The yellowish wood just in front of the white wall panel, and the wall panel in the background at 24mm f4 looks actually quite sharp compared to the fuzzy text on the box, which really does not look sharp and simply could be out of focus.
