<p>Years ago when the digital cameras were not as sensitive as today AF fine-tune wasn't as necessary because you couldn't see the imperfections. Now, we have wonderful new cameras that are so good and highly sensitive that every imperfection in the lens and focus shows up. Thus the reason to make fine-tune adjustments. Like a fine musical instrument needs to be set up, such a professional guitar, a professional quality digital camera needs to be set up as well. AF fine-tune is one of these set-ups among other adjustments. You can do it yourself if you prefer. I personally take my new cameras along with lenses to an authorized Nikon service center and they set up my camera along with all my lenses. I get fantastic results. <br>
Any time you hear or read a review about a camera or lens not performing up to par it may be that the photographer never took the time or effort to have his gear professionally set-up by a Nikon authorize service center. Of course, that may not have been the only reason. It could have been user error on the part of the photographer.<br>
Just my 2 cents.</p>
