The Nikon Z 7 is the company's first full-frame mirrorless camera: a 46MP,
4K-capable machine built around a variant of the D850's BSI CMOS chip, but
with the addition of on-sensor phase detection. It's designed to offer an
experience familiar to existing Nikon DSLR shooters in a smaller, lighter
camera. The Z 7 is based around the all-new Nikon Z-mount but an adapter is
available for use with existing Nikkor F-mount lenses.
We were lucky enough to get our hands on a pre-production camera before
launch and we're impressed, despite the model we used running very early
firmware. The build quality is great and the interface is responsive, while
JPEG images show pleasing color and good detail. From our initial
impressions of image quality it also seems that the camera balances noise
and detail retention well as light levels drop.
We have a few reservations regarding the autofocus interface on our pre-
production camera (though its accuracy was quite good), but overall, the Z 7
we used felt very polished. This is all the more impressive given that the
Z 7 is Nikon's first entrant in the full-frame mirrorless space and the
company is clearly aiming it at the higher-end of the market.
Key features:
45.7MP BSI-CMOS sensor with on-sensor phase detection
In-body 5-axis stabilization (rated to 5EV)
493 PDAF points with 90% horizontal and vertical coverage
ISO 64-25,600 (expandable to 102,400)
Up to 9 fps shooting (JPEG and 12-bit Raw)
3.69M-dot OLED viewfinder
2.1M-dot tilting touch LCD
OLED top plate display
Single XQD card slot
UHD 4K capture up to 30p
10-bit 4:2:2 N-Log output over HDMI
Up to 100Mbps H.264 8-bit internal video capture
SnapBridge Wi-Fi system with Bluetooth, including to-PC transfer
We see the Z 7 as not only a 'D850 without a mirror', but also (perhaps more
) 'a D850 with a more consistent stills/video experience and greatly
improved video AF.' And straight out of the gate, that makes it a pretty
well-rounded do-everything camera.
Three 'Z-mount' lenses will be available initially: a 35mm F1.8, a 50mm F1.8
and a 24-70mm F4. Nikon has also announced it is developing a 58mm F0.95 '
Noct' lens and has published a roadmap to show how it plans to expand the
system. A battery grip will also be available at some point, but a release
date hasn't yet been set.
Three Nikkor S (for 'silver') lenses will be available for the Z-mount
initially: a 50mm F1.8, a 24-70mm F4 and a 35mm F1.8
Nikon has also released an F-to-Z mount adapter (formally known as the FTZ
adapter) that will allow the use of F-mount lenses on the new cameras. This
has a mechanical aperture lever built in, allowing full use of AF-S and AF-I
lenses. Older AF-D lenses will offer auto exposure and AI lenses will have
full metering. There's no aperture tab for use with 'AI' or older lenses,
though.

Video
Nikon has done a lot to enhance the Z 7's video, even if that's not
immediately obvious from the specs.

Thoughts so far
What does the Z 7 say about Nikon's direction, who its trying to appeal to
and what does it mean for F-mount users?
