Thank you Eric for some good help on Auto Focus checking, did your DOF test with lens at F5.6 focus spot on and not too far forward as you said it might be.
Re the new memory features: Pix No 1 is Memory Recall
Pix No2 Mem Set and when holding camera is on the right side near lens mount. No 3 is Focus Function button and these are at end of lens above focus ring, there are 4 of them I each at Top, Bottom, L & R. You can also use them to use auto focus at any time.
To use to store a focus point (eg a post top a bird may come to) set recall to AF-L, focus on post and press Memory Set to save it now return Mem Recall to centre position. Carry on using camera in normal way. If bird comes to post as stored all you need to do is press any one of the 4 Focus Function Bottons at end of lens.Setting is not lost if you turn camera off.
I have also reset as per a3 in D850 book: focur tracking to Quick and Subject Morion to Erratic for birds. New lens now working very well focus sorted! QED it works well. Took me some time to sort out but all info in instructions for new lens plus D850 instruction book.
Good to see you are making progress Graham. I see from bottom of your photo 1 it's even got a music button
One point on the Tracking settings. If you have the speed set to Quick it will grab focus as it sees something quickly.
BUT... if the moving subject you are tracking goes behind another object ( for eg a bird flies behind a tree) the focus will Quickly switch to the tree in front. If you set the focus's speed more towards Delayed ...it does just that. It waits a moment before shifting focus to the tree. So doing, it gives the bird time to emerge from the other side of the tree still in focus.
It's one of those catch 22 situations.
I could imaging trackingðŸ¦ðŸ¦“ðŸ¦ðŸ— moving through long grass in Kenya it might recommend more Delayed weighting to keep focus locked.
