>>4299356My D750 was stolen along with my 24-70 2.8 lens. I initially bought a Z6ii, ran it with a few of my other lenses, and a few months later bought a 24-70 2.8 S. The Z6ii sucked. I hate a lot about it, the lack of physical controls (lots of scrolling through menus), the automated features are half baked and unreliable. Mine also had a weird issue where the EVF would only work intermittently in 50F or below weather, which is about 8 months of the of the year here.I bought the camera used off Amazon like a moron, and it was grey market, so no chance of getting it repaired.
Outside of the stated mechanical issues with the camera, the quality of life issues were frustrating. It took about a second to switch from the back screen to the EVF. There's not enough buttons to map all the controls you'd like, the black out when shooting at high frame rates (for wildlife) made it impossible to follow subjects, and the face detect features were so unreliable I would not trust them for paid shoots.
I ended up upgrading to a Z8 a few weeks ago. If you have lenses for Nikon, I'd skip the Z6 and Z7, and go straight for the Z8/Z9 at this point. Coming from the D750 and D4, the Z8 actually feels like an upgrade. The improved Mega-pickles, it switches from the back screen to the EVF in about 30ms, no black out, and the additional buttons for ISO, bracketing, metering modes, and auto focus modes make the decision of what to assign the customizable buttons less of a chore.
