I don't think so. You might not get the very most out of the D850 but I've heard that it's so great that you can just set it on a rock on Auto and let it go. It will make it's own exposures, e-mail them to your friends and family, decide which ones are the best and send them to the printer and they will be framed and on your wall by the time you get home!
Seriously, it's just a camera. Take it and have fun!
You may not use it’s full potential but it’s just a camera with buttons for most key settings. Spend some time on the autofocus system but keep it simple. Have some fun.
