Thanks for the comments and encouragement Everyone
The camera seems to be working properly and I'm having a gas shooting one of my favorite subjects with a 27 year old AF 105mm f/2.8, there is something endearing about the sound of the focus working
1/6", f/5, iso 1250 !
We are finally out of the deep freeze so I hope to get out and about and play with my AF-P DX 10-20mm VR next.
