Sorry for my absence the last couple of weeks. I had camera problems and just replaced it on Saturday. I ended up with a Nikon D500. Today I spent some time fine tuning my 150-600mm lens. I will test it for a couple of days to see how accurately I adjusted it. Hope I got it right. Now to go through the rest of my lenses. Good to be back.
@thewatersphotos, I also shot with a 7100, but it had some issues which couldn't be corrected. I went with the d500 mainly for 2 reasons. First was the 10 shots per second and the second was it should be pretty good in low light. Hopefully the noise won't be to bad. I bought it used from a camera store. I was considering the d850 but the salesperson thought the 500 would be better for me. It also allowed me to keep and use all of my lenses.
