I believe that the problems with the 500 PF/D850 combo goo deeper than focus fine-tuning. With that combo, AF performance suffers considerably as you move the AF point away from the center …

I have found the exact same problem with the D850+600+1.4x TC. I have fine-tuned many times, tried the same body + TC combo on other lenses, and even bought a new TC to ensure that was not the issue. Still have a lack AF consistency. It’s frustrating because without a TC the D850 is an unbelievable body. I find myself using my D5 more because of this, as haven’t experienced the same issues with it. No complaints most of the time because I love the high ISO performance and FPS, but when I have to crop more than a little, I sure wished I had the pixels of the D850 with 1.4x…

I thought I was crazy but glad to see I am not the only one who has experienced this.

Best,
Mike
