Can agree with all of this.
What I don't get is why, after all the hype of the Z mount, why didn't they leverage it. Nikon is shipping an FF camera with a 50 1.8, and 35 1.8, and a 24-70 f4.
They should have shipped with something that just didn't exist on other platforms. The coming 58 f0.95 might be good, but could you imagine the hype if that 24-70 were an f1.8? Okay, I know prime lovers wouldn't care, but Nikon would have a lens you just couldn't get on other platforms. That would be a hook some people couldn't resist.
Worse, looking at the roadmap, there isn't anything even on the plan that is truly new ground (a 50 f1.2 is not something to make me rush out and pre-order a Z7). The adapter is nice, but at price, why not get a D850 and wait another generation if you're already heavy in Nikon, or switch to Sony if you want FF with native lenses, or Fuji/M43?
What does the Z7 offer that you can't beat elsewhere?
Same as the A7 initial release lenses... 55 f1.8, 35 f2.8 and 28-70 f3.5-f5.6....
