Reference excerpt

Nikon Z-mount (stylised as Z {\displaystyle \mathbb {Z} } ) is an interchangeable lens mount developed by Nikon for its mirrorless digital cameras. It was first used in 2018. With the introduction of the Z-mount, Nikon discontinued its previous mirrorless mount, the Nikon 1 series.

Z-mount characteristics

Throat diameter The 55 mm throat diameter of the Nikon Z-mount makes it the largest full-frame lens mount. It is much larger than the older Nikon F-mount (44 mm) and than the Sony mirrorless E-mount (46.1 mm), but only slightly larger than the 54 mm of both the Canon EF and RF mounts. It is also slightly larger than the 51.6 mm diameter full-frame mirrorless Leica L-Mount.

Flange distance The Z-mount has a very short flange distance of 16 mm, which is shorter than all previously mentioned lens mounts. The shorter flange distance allowed Nikon (and others) to build smaller and simpler lenses. This flange distance, along with the large throat diameter, allows for numerous lenses of nearly all other current and previous mounts to be used with an appropriate lens mount adapter on a Z-mount camera (see Autofocus/electronic adapters for a list of mounts and adapters).

Lens contacts The number of electrical contacts between the camera body and lens was increased from eight (on the F-mount) to eleven (on the Z-mount). These communicate lens information to the camera and provide power and instructions to the lens from the camera.

Mount type and tabs As on most interchangeable lens mount camera systems, the Z-mount uses a bayonet mount for attaching the lens to the camera. It increased the number of tabs from three (on the F-mount) to four. This provides slightly more security on the mounted lens.

Lens formats: FX and DX For its two sensor sizes, FX (Full-frame) and DX (APS-C), Nikon develops two varieties of lens. The two versions both use the Z-mount, and are mechanically and electronically identical. When mounted on the same camera type (i.e., an FX lens on an FX camera or a DX lens on a DX camera), a lens performs according to its nominal characteristics. When a DX lens is mounted on an FX camera, it causes the camera to use a crop mode from the center of the sensor, corresponding to the DX coverage of the lens. When an FX lens is mounted on a DX camera, it provides a 1.5x crop field of view, as is typical with an APS-C camera.

Lens mounting Z-mount lenses lock (i.e., attach to the camera) by aligning the white dots on the camera body and lens and turning the lens counter-clockwise (when looking at the front of lens). To unlock, the camera's Lens Release button is pressed and the lens is rotated clockwise.

Z-mount cameras

Introduction of the cameras In late 2018, Nikon released the first two cameras (alongside three lenses and the FTZ converter) that use this mount, the full-frame Nikon Z7 and Nikon Z6, both using the then top‑of‑the‑line Expeed 6 image processor. In late 2019 Nikon announced their first Z-mount camera with an APS-C sensor, the Nikon Z50, also using the Expeed 6. In July 2020 the entry-level full-frame Z5 was introduced. In October 2020, Nikon announced the Nikon Z6II and Nikon Z7II, which succeed the Z6 and Z7, respectively. Both used dual Expeed 6 image processors. The APS-C lineup was expanded in July 2021, with the introduction of the retro-styled Nikon Zfc. In October 2021, Nikon unveiled the Nikon Z9, which effectively succeeded the brand's flagship D6 DSLR. It was the first to use the Expeed 7 processor. The APS-C lineup was further expanded with the Nikon Z30, announced at the end of June 2022. 2023 brought the introduction of the Z8 and Zf, the second and third cameras to use the Expeed 7. The Nikon Z6III was announced in June 2024. In November 2024, Nikon announced the Z50II as a major upgrade of the Z50; it became the first APS-C camera to use the Expeed 7 processor introduced with the Z9. In April 2025, Nikon announced the Z5II as a major upgrade for its lowest class full-frame line of cameras. In September 2025, Nikon announced the first camera of its "Z Cinema" line, the ZR, co-designed with RED. The ZR is the first Nikon camera that offers the 12-bit R3D NE raw video codec (Redcode Raw with TicoRAW) internally.

Camera overview The following table contains the specifications for all Nikon Z-mount cameras, including models that have been discontinued.

Notes

Red cinema cameras

In 2024, Red Digital Cinema was acquired by Nikon. In 2025, the first two cinema cameras using the Z-mount, the V-RAPTOR [X] and the KOMODO-X, were released. On 9 September 2025, Red released the V‑RAPTOR XE, also offering a Z-mount version besides the RF-mount variant. Along with the ZR, they are all part of the Z Cinema line.

Z-mount lenses

With the introduction of the Z-mount, Nikon began designing and releasing a new set of lens for that mount. It published a roadmap outlining forthcoming lenses when the Z-mount system was initially announced. The roadmap has been updated multiple times. As of February 2025, all lenses in the last version of the roadmap from September 2023 were released. Several lenses which were not indicated on the roadmap were released as well. On October 30, 2024, Nikon announced that it was developing a video-centric, standard zoom lens with power zoom, the NIKKOR Z 28-135mm f/4 PZ. On February 13, 2025, the details of the lens were released, alongside the announcement of the first two RED Digital Cinema cinema cameras with Z-mounts, the V-Raptor [X] and Komodo-X. In 2018, Nikon announced the development of the Z-mount 58 mm f/0.95 S Noct lens, reintroducing the Noct brand, which was historically used by Nikon for lenses with ultra-fast maximum apertures. The lens was released in October 2019.

Lens designations In their labeling of lenses, in addition to focal length and aperture, Nikon uses a new designation system (i.e., various tags) for their Z-mount lenses. The older F-mount Nikkor designations are no longer used, though they overlap in some areas (e.g., the VR and DX labels). Nikon also introduced the S (for S-Line) branding for especially high-performance ("superior") lenses, which is akin to Canon's L designation or Sony's G or GM branding.

Lens lines The Nikkor Z line-up has several distinct lines of lenses, which are designed with similar handling and optical characteristics.

Worked examples

Example 1 — a first encounter with Nikon Z-mount

Start with the simplest possible case. Write down what Nikon Z-mount claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nikon Z-mount before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nikon Z-mount ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nikon Z-mount

In research: Nikon Z-mount appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nikon Z-mount in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nikon Z-mount is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lens mounts, Nikon, Nikon Z-mount cameras, so understanding it makes those chapters shorter.
In everyday life: Look for Nikon Z-mount outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
