I followed the directions carefully. The condensed version is that you focus in Live View and then press two buttons simultaneously for the camera to do the job for you without the usual trial and error. The camera "clicks", the mirror goes down, and it the camera comes up with a value anywhere from -20 to +20 for a given lens.
I spent an hour doing this with four lenses, two of them G lenses and two D (screw drive) lenses. The values returned were not consistent and were all over the place. I tried using 4 different high contrast targets that I printed out from the internet. Different targets produced different results, and they weren't even close to one another. I'd reposition the camera a bit and the results would change. I'd get results from -13 to +4 on one lens in particular. I put a 50mm f/1.4 AF-D on the camera, and the first result was -20. At that point, I decided to forget the whole thing and turn off the AF Fine Tune feature. I can't trust these results. I'm not even sure I needed to do this. I took pictures with all three lenses after getting the camera and didn't see any problems.
Did I do anything wrong? I don't think so. I followed the directions to the letter.

Hi, I think Steve Perry's video would be of great help. https://backcountrygallery.com/?s=AF+Fine+Tune
