Nikon camera fans finally get some real mirrorless options, including the company's first foray into in-body image stabilization.
It's been a long wait, but now we can exhale: Nikon's full-frame mirrorless Z series is ready to soothe the tempers of frustrated Nikonians. There isn't a lot in the Z7 and Z6 to turn owners green with envy. But Nikon pros will have nothing to feel embarrassed about and for the most part should be happy with Nikon's offering, which also seems solid enough to attract some newcomers. The wildcard? Canon, which is . But as the unfashionable latecomer, it's facing some stiff competition.
Nikon's strategy follows Sony's to a certain extent: two models, one high-end, one midrange. They have identical bodies differentiated predominantly by the sensor. The Z7 and Z6 differ in important ways: the Z7 has a 45.7-megapixel BSI CMOS sensor, no blurring optical low-pass filter and slightly better tonal capture in bright light. Meanwhile the Z6 uses a 24.5MP BSI CMOS with an OLPF and has slightly better tonality in dim light. The resolution difference also means the Z7 has slower continuous-shooting performance -- it's processing a lot more data. They also have different autofocus-area density, probably because there are more on-chip phase detection sensors in a chip with more pixels.
In addition to the cameras, Nikon launched the first three lenses for the Z mount in conjunction with a new "S" designation for its premium lens models. They're optimized for the new system: a 35mm f1.8 S, 50mm f1.8 S and a 24-70mm f4 S.
The Nikon Z7 will ship by the end of September, with the body selling for only $3,400 or $4,000 with the 24-70mm f4 lens. The Z6 won't be ready until late November, its body selling for $2,000 and $2,600 for a kit with the same lens. We don't have prices or availability for other regions, but those convert to about £2,600 or AU$4,760 and £3,100 or AU$5,450 for the Z7 and £1,550 or AU$2,720 and £2,010 or AU$3,500 for the Z6.
The 35mm ($850) and 24-70mm ($1,000) lenses, plus the $250 Mount Adapter FTZ will be available at the same time as the Z7, while the $600 50mm will follow by the end of October. If you buy the FTZ with one of the bodies before the end of the year, Nikon will shave $100 off the price.
While the Z7 seems the more interesting, the Z6 will probably be more popular -- the price is much more approachable if you don't need the high resolution, and most people probably don't.
The Z7 is basically a mirrorless adaptation of the excellent but burdensome, while the Z6 is an up-to-date prosumer full frame (the and are a bit old at this point). Nikon seems to have made a strong effort to make sure the system hits the ground running -- the FTZ converter allows almost all of the F-mount lenses to work on the Zs, and is able to take advantage of the sensor-shift image stabilization and autofocus (if the lens supports it). That's important because Nikon's late to the game and doesn't have the luxury to roll out new lenses slowly.
And the body's designed to support the large DSLR lenses, with a huge grip for balanced handling. It also supports most of the existing accessories, including the batteries from the D850 and, and has the same dust-and-weather resistant build quality as the D850, as well as the sturdy magnesium alloy construction. The viewfinder has a fluorine coating to help repel the various detritus that piles up against it.
Nikon also did a pretty good job future-proofing the series. The new, wide lens mount (one of the biggest in this class at 55mm), allows for superfast (wide aperture) lenses, one of the latest want-to-haves among a large niche of photographers. Nikon has a 58mm f0.95 in the works, along with a new coating to improve image quality.
The bodies incorporate a USB-C connection which supports charging rather than the dated USB 2.0 or humongous USB 3.1, as well as 802.11ac-standard Wi-Fi for faster, more stable wireless transfers. Though they ship with XQD card support, adding CF Express is just a matter of a forthcoming firmware update (the card slots for the two are the same).
The body design doesn't scream "innovative," but on first feel it does hit almost all the important checkboxes; it's smaller and lighter than a comparable DSLR (), roughly the size of the latest Sony A7 bodies. On first glance, I was hoping for more manual controls on top instead of the status LCD. With an EVF and a back LCD which both can convey the same information, top status displays frequently feel superfluous. I'll know more after I get to shoot with it later Thursday.
As for video, the epiphanic joy the Nikon folks expressed when they realized how much better the mirrorless experience is for shooting video than a DSLR says it all. It's sad that they've been missing out all these years. The Zs have all the essential video-shooting capabilities, such as 4K UHD/30p and 1080/120p for slow motion (on the Z7 in DX mode it uses a full-pixel readout), N-Log 10-bit HDMI out to a recorder simultaneously with 8-bit internal. There's an N-Log display profile for on-camera playback, a headphone jack for monitoring audio output, time code support and manual focus peaking. It can also do 8K time-lapse movies.

The new lenses look and feel a lot simpler and more streamlined than the traditional Nikkor designs, but the primes seem surprisingly big. Unlike the F-mount models, these are designed to be quiet and smooth with video in mind, sporting electromagnetic diaphrams (for fast, silent exposure adjustment). The two primes have nine-blade apertures for sweet bokeh (the 24-70mm f4 has seven blades), and all have the control ring popular on advanced compacts that can be used for manual focus or programmed for another function.
Nikon has an aggressive roadmap for lens releases, but the two essential staples for pros, a 24-70mm f2.8 and 70-200mm f2.8, aren't coming out until next year.
My biggest question is battery life. Nikon doesn't mention it anywhere, and mirrorless cameras have notoriously miserable power profiles -- it took Sony years to offer a longer-lasting battery with the A9. There's a two-battery pack (MB-N10) in development, but no ETA attached to its release. The company says it will increase shots or movie recording time by 1.8x, but normally the rated increase is one-for-one; add another battery, get twice the life. Two batteries should deliver way more.
The metering sensitivity in bright light also looks a bit low, maxing out at 17EV, and autofocus sensitivity only goes up to 19EV. Almost every modern camera can go up to 20EV. Bright sunlight is about 15 EV so it's probably an edge case, but for shooting water or winter sports it might become an issue. And along those lines, the flash sync speed is only 1/200 sec, which makes using flash to stop action suboptimal, though it does support Nikon's Auto FP sync which can compensate.
Finally, it has a single card slot. Meh.
Check back for an update about my experiences shooting with the Z7 and some photo samples if I can swing it.
