Should she be looking at something else? She will divorce me if she feels like she's using something inferior, lol. She enjoys taking photos too. She's been using a Canon Rebel for years and we thought about consolidating. If there is a better option for companion cameras I'm all ears.
You can get a Z6 and maybe a D850...used or something I don't know, she gets the better camera though. This is a really specific caveat in here.
The original idea was a Z6 and a D7200. She'd be real happy with that camera. It's not a deal breaker, just an idea we had if we could make it work. She had a Canon t7i but I hated it on the occasions I had to use it. Not that it was a bad camera I just found it harder to use than the Nikon.
