All,
If you are struggling with the New Function in the D5/D500 Auto Fine Tune Workflow like I did, here is my Work Flow:
My D500 Auto Fine Tune workflow :
12) Repeat 7, 8, 9, 10, 11, 12 several times to insure consistency
13) Take the high and the low values out, average the rest = use this value as the Final AF Fine Tune Saved Value (OPTIONAL STEP ONLY)
I see that you already had the correction for leaving in on. Do you realize that your steps, when you add 12 and 13, basically mimic the Dot Tune method? As it happened, I did the same as I wanted to verify. One nice thing is that much like Dot Tune, if you do step 12, you are factoring in the inherent variability of AF.
I was not aware that Dot Tune did that. I have always learned that there are always outlier in most sampling systems, to me that is noise and needs to be cleaned or filtered, I think I finally applied something from my statistics class...LOL
One thing that I found was that I needed to be quite cautious to not move the camera as I was doing the "double-press" on the two buttons. Once I got my fingers properly set, it worked much easier, and more consistent.
I observed that as well, the first few lenses I Auto tuned, the variability was large and as I tuned more (I have 7 FF lenses) the tighter my variation become. My last batch (lens : 70-200 VRII) was +/- 1/2!!!!!
Testing with Dot Tune and my Focus Tune target I was quite happy how well it worked. Did my 300 f4 PF and my 600mm f4 with all 3 TC's. Quite nice and quick to boot.
It would probably be best if there is a way to Push the two buttons wirelessly - Via SnapBridge to avoid any mechanical vibration, I bet you I can write that code if Nikon gives me the source code or a developer's kit.......I will not hold my breath on that LOL.
