99 things you need to know about Nikon's full-frame mirrorless camera system

21. Three new Z lenses at launch

Nikon has announced a new S range of lenses to accompany the Z7 and Z6, and three lenses will be made available this year. These are the NIKKOR Z 24-70mm f/4 S, NIKKOR Z 35mm f/1.8 S and NIKKOR Z 50mm f/1.8 S. The 24-70mm will go on sale with the Z7 in September, and the 50mm will appear with the Z6 before Christmas.

22. NIKKOR Z 58mm f/0.95 S Noct

Nikon has also announced the development of NIKKOR Z 58mm f/0.95 S Noct, a manual-focus lens with a particularly wide aperture. Set to head up the S line of optics, the lens inherits the design concept behind the original AI Noct-Nikkor 58mm f/1.2 that was released in the 70s, and is said to “symbolise the Nikon Z mount system's new dimension in optical performance.” 

23. FTZ adapter

The FTZ adapter allows for hundreds of F-mount lenses to be used on the two new bodies, with support for auto-exposure. Around 93 lenses will have additional support for autofocus, meaning that they should behave just as they would if mounted on a DSLR. 

24. Four clips - not three

Unlike the F-mount that holds lenses in place by three clips, the Z mount makes use of four. Nikon states that if the Z mount were to also use three clips, they would need to be longer and thicker because of the difference in inner diameter size. By using four short clips, the strength of the mount is improved, and these allow for a shorter angle of rotation when removing and attaching lenses.

25. Easier to develop video and super telephoto lenses

One of the benefits of the new mount is that Nikon can develop the kinds of lenses that are more difficult to develop for the F mount – and not just in terms of maximum aperture. Nikon cites lenses intended for video recording and super-telephoto types as two such examples.

26. Better communication than F mount

This large-diameter mount, which works with a fresh line of lenses, has 11 contacts, which are said to increase both speed and volume of data communication between the camera and lens for greater AF accuracy and image quality.  

27. Stainless steel and brass mounts

While the cameras’ bayonet Z mount is crafted from stainless steel, the fitting at the back of S-series lenses is crafted from brass.

28. Nano Crystal Coating on every lens

Nano Crystal coating is currently only used in selected F-mount lenses, typically those aimed at enthusiasts and professionals. Here, Nikon has chosen to use it in every S-series lens, which bodes very well for image quality.

29. New ARNEO coating

In addition to the Nano Crystal Coat, there’s also a new ARNEO anti-reflective coating that’s said to offer almost the same level of anti-reflective performance.

30. Sealed with a silver ring

In contrast to the gold rings used around many modern F-mount lenses, all S-line lenses are to be designed with a silver ring around their barrel. This is said to shine when the light catches it at certain angles.
