| Successor | Nikon Z 7II |
Three Z-mount lenses were available by December 2018, the Nikkor Z 24-70mm f/4 S FX AF, the 35mm f/1.8 S FX AF and the 50mm f/1.8 S FX AF. The F-to-Z mount adapter accessory allows for using Nikon lenses from the digital SLR series with full compatibility.[3]
In late 2018, Nikon also published a "roadmap" of lenses to be released between 2019 and 2021. A total of nine products were included in that list.[4]
The Nikon Z7 was succeeded by the Nikon Z 7II in October 2020.

The Z6 and Z7 share firmware updates with only minor differences due to the different sensors.
After completing their test of the new camera, the Digital Photography Review web site provided this conclusion: "The Nikon Z7 ... is also its most well-rounded camera for stills and video, and an exciting indicator for what's to come from the 101 year-old company. But first generation products are rarely perfect, and the Nikon Z7 is no exception". The overall score was 89%.
The positive specifics were briefly stated: "the camera feels, handles, and operates like a smaller, lighter full-frame Nikon DSLR - from button placement to menu layout, to the robustness of the build quality and the comfort of the grip. But there are some small differences, namely in the way the AF system operates. It is also the first Nikon full-framer with a truly useful silent shutter and mechanical in-body stabilization. On the cinema side it offers a wide variety of 4K video capture options that should satisfy both home-movie-makers and advanced videographers alike, but possibly not established professionals".
The site provided this summary of the less positive aspects: "the Z7 technically offers the same calculated Raw dynamic range as the D850, on sensor AF points lead to banding/striping which limits usable DR [dynamic range]. Autofocus, while reliable in good light, hunts more than we'd like as light levels drop. And AF tracking as a whole lags behind the competition, as well as Nikon's own full-frame DSLRs, both in terms of reliability and usability".[6] (All of these issues were dealt with in subsequent firmware updates. The autofocus became far more reliable and the banding issue was dealt with. It might be important to mention that all digital cameras suffer to some degree from this phenomenon caused by amplification of the signal. If the data isn't decoded correctly, the amplification artifacts can and do happen.)
In 2018, when the Z7 was released, there were some real issues in the photographic community regarding incorrect information or outright defamation. The Z7 was certainly a victim of this trend. Though a touch behind the overall market on level of technological advancement the Z7 was a strong contender and an excellent first build of a mirrorless camera by Nikon. Most of the initial issues with the camera were dealt with either entirely or almost entirely with consequential firmware updates.
This camera would prove to be the pivotal move for Nikon to enter the mirrorless camera market and the beginning of their mirrorless journey culminating in the current era Z8 and Z9 cameras which are some of the highest performing mirrorless cameras available on the market today (2024).
