Well I wasn't expecting too much. Some good changes, but also a lot of recycled specs as well.
Missing or the same
Same EVF (but it was already a good one, though the newer 5mp one would have been nice like Canon and Panasonic).
no internal 10 bit video,
Z6 with 4k 60 at DX crop only (and even then only via a promised firmware upgrade next year).
Same sensors as MK1 versions (although to be fair that's not a bad thing).
No 8K option (although not something I'd ever use).
No UI changes (that I've read about)
New
Dual card slot (2nd one being SDXC UHS II),
3 times the buffer capacity on both Z6 II and Z7 II,
ability to use eye AF in wide area modes, and eye AF for video.
Being able to use the camera whilst powered off an external battery.
Z6 max long exposure time now 800 seconds (or something like that).
Proper battery grip with shutter release controls (though sadly not compatible with the mark 1 Z's).
Slightly faster frame rates
Promised better AF and more low light capability (though remains to be proven when the reviews start coming in).
HDR HLG video recording
What's your thoughts ? Pricing as mentioned seems pretty aggressive, but TBH, there's not whole lot to tempt me to lose a fortune on my current Z's and upgrade. To me, this is what the Z camera's should have been at launch, and we should now be on a proper 2nd generation to compete with the best of Canon and Sony. Don't get me wrong, Nikon did a lot of things brilliantly with the Z's as their first full frame mirrorless offerings, but the competition doesn't sit still, and with an ever shrinking market, you really need some stand out features to capture sales, and respectfully, nothing in the MK2 cameras offers anything new that other's haven't been already doing (and some even better). I can see a lot of bashing come Nikon's way from the Canon and Sony fanboys.
Anyway, It's lenses for me now. Come on Nikon, launch that 200-600 Z mount on your roadmap.
