Nothing scientific or elaborate. I shot an object at f2.8 and 135mm. I chose this at the time because that’s where I was expecting to use it for my next shoot. Then I manually focused to get the sharpest shot I could. Then did a series of shots adjusting af-fine tune and refocusing. I then reviewed the shots to determine the one closest to my sharp manually focused shot. Then I went through the same procedure but narrowed down the range of af-tuning I tested. In my case I was lucky and it worked well through the zoom range.

Quick and dirty but worked for me until I got Tokina to adjust it.
