Beautiful storm photographs Jess!
I am a fellow Nikon photographer and currently have a D750. I spend a lot of time wondering what I would upgrade to next. If the Nikon Z range didn't have a different lens fitting, it would be a no brainer to stick with Nikon. But if I wanted to go mirrorless then it would be almost be as easy to swap brands and buy new glass. Thankfully I'm an amateur and I have a perfectly good camera, and so most of my daydreaming about cameras will remain just that. I wont have to make any tough decisions for a while if I don't want to. From what I've heard, the D850 is an amazing camera, and I am very jealous of your camera setup! :)
I understand those feelings Cath! I am curious about the newer adapter that Nikon just released that should allow all our F lenses to work with the Z bodies, but I just wasn't brave enough to take the leap and find out yet! I know at the end of the day it's not the camera that makes the image, it's the photographer.. but I hope it will serve me well to boost my image quality! The D750 is a fantastic camera too and no need to really upgrade unless you have to!
Ooooh! I didn't know that Nikon had a new adapter out. I'll do a bit of research on that. Thanks for the intel. More food for thought when I am fantasy camera shopping.... Enjoy your D850!
