I got mine in January of this year, 2 days before leaving for a California Central Coast workshop. Which, with the complexity of the D850, I do not advise. Mastering the D850 isn't easy. Less than excellent lenses show all their flaws in 56 Mb images. The capabilities of the D850 system will blow your mind. Focus Stacking, in particular, has taken my Landscapes to another level. Here are a few images taken with the D850.
Looking forward to giving that a try. What software did you use?
