Not me. What I would have wanted was an updated Z7 ii, at a Z7 ii price and Z7 ii weight, but with upgraded AF. I don’t think you need a stacked sensor to achieve better AF than the Z7 ii. I’m not too disappointed though. I’m more of a landscape photographer so the Z7 ii still works for me.
I think it will be a big hit, and many people were waiting for exactly this. Nikon really hasn't done anything like this since the D3/D700.
Personally I don't need a $4000 camera, my Z6 does just fine, and if I dunk it at some point it would cost $1000 to replace. They will sell a lot of these I think.
Nikon was at the top of their game back then. I had a D3 back in those days. Back then, you could sale a used Nikon lens for near retail, in ONE DAY on craigslist. It was nuts. I've never seen Nikon craze like that before.
Let's not reinvent history. Up to the time the Nikon D3 appeared, the popular opinion was that Nikon was toast. Canon had been in full frame for some time, The D2 series was regarded as a failure (within Nikon, as well; many got permanent "offices with windows" due that generation design). The D3 put Nikon back in the game, but they'd already lost a lot of market share to Canon by the time it appeared.
That said, the combination of D3, D3s, D3x, D300, and D700 actually eventually did help Nikon regain market share against Canon, to the point as I outlined at the time of temporarily passing Canon in market share.
The real craziness of the D3/D300 launch was that Nikon wasn't prepared for the resurgence of orders. The "welcome back" response was greater than they anticipated. We saw that happen again with the Z9 recently. I'm not sure the Z8 is a repeat of that, though.
Canon first came out with the full-frame 1Ds in 2002 at a whopping $8000 price tag, followed by a more affordable 5D in 2005 for $3000. By the time the D3 came along on August 23, 2007, Canon already had FX for 5 years, and 2 years with "affordable" FX. Hence Nikon was desperate to send out a $3000 D700.
I recall that back in 2007, Nikon was producing 8K D3 and 80K D300 a month, but there was never any D300 shortage. I never pre-ordered and just bought a D300 off the shelf from my then local store Keeble and Shuchat before Thanksgiving 2007, along with an MB-D10.
I certainly don't see a Z9-style shortage for the Z8, but even so, the Z9 shortage lasted about 8, 9 months in the beginning of 2022. By August, September 2022, one could order one and receive it within a couple of weeks. The first time I saw the Z9 in stock @ B&H was October 2022, but that didn't last very long. IMO, any initial Z8 shortage will be modest, if there is any at all, based on Ricci's comment that Nikon is producing 12K Z8 a month.
