A preferred focal size for road images and general-purpose use, it encompasses a vibrant f1.2 focal ratio gathering two instances the sunshine of its smaller sibling the Z 50mm f1.eight S, though nonetheless half a cease slower than the famed Z 58mm f0.95 Noct. On a cropped physique just like the Z50 the brand new lens is equal in angle-of-view and depth-of-field to a 75mm f1.7 lens. That is fairly engaging for portrait images and offers good background isolation and blur even on the smaller format sensor.

Details from the catalog
Let’s examine the Nikon Z 50mm f1.2 S to the Nikon Z 50mm f1.eight S and Nikon Z 58mm f0.95 Noct (“Z Noct” for brief). As common I’ve rated the options with a [+] (or [++]), when it’s higher than common and even state-of-the-art, a  if it’s customary or simply common, and [-] if there’s a drawback.
Dimension (diameter x size): 90 x 150mm (3.6 x 6.0in.). Including 60mm for the lens hood offers a complete size of 210mm which makes the brand new Z-Nikkor longer than the Z Noct at 102 x 153mm + 29mm lens hood. The Z 50mm f1.eight S is barely 76 x 87mm + 40mm lens hood. The photographs beneath present the part of every lens at a comparable scale. [-]
Weight: 1084g (38.2 oz.) plus 56g for the lens hood. The Z Noct is 1997g + 58g lens hood, the Z 50mm f1.eight S is 412g + 27g lens hood. 
Optics: The Nikon Z 50mm f1.2 S is a fairly advanced design with 17 components in 15 teams together with 2 particular dispersion components and three aspherical components. That is just like the Z Noct (17 components in 10 teams) however way more advanced than the Z 50mm f1.eight S (12 components in 9 teams). 30 glass/air surfaces create a number of alternatives the place reflections could cause issues. To counter this the Z 50mm f1.2 S employs the brand new “ARNEO” anti-reflective coating (similar to the Z Noct) along with Nikon’s Nano-coating to cut back flare, glare and ghosting. However it misses the fluorine-coating the Z Noct (and plenty of Z zoom lenses) has on the entrance component to repel water, mud, and filth and make cleansing simpler. [+]
Closest focus distance is 0.43m (1.41ft.) in guide focusing with a magnification of 1:6.1 which isn’t a lot. This ends in a working distance of 0.26m. The Z Noct goes all the way down to 0.5m with a magnification of 1:4.9, the Z 50mm f1.eight S achieves a magnification of 1:6 at 0.38m object distance in guide focus. A magnification of 1:10 is achieved at a distance of 0.64m. 
Filter-thread: 82mm, similar to the Z Noct. The Z 50mm f1.eight S wants a lot smaller 62mm filters. 
Picture stabilization: The lens affords no optical stabilization – like each Z-Nikkor prime lens thus far. However the Nikon Z full-frame our bodies present built-in sensor-shift stabilization for Z-mount lenses over 5 axis – plus an optionally available digital stabilization in video mode. 
Auto focus: Sure with built-in AF drive, similar to the Z 50mm f1.eight S. Handbook-focus override is by merely turning the devoted focus ring. The main target ring has a mildly variable gearing overlaying the main target vary in 60 levels when turned (not too) quick and about 180 levels when turned slowly. This – along with the restricted AF-speed in Film Mode – makes easy focus pulling simpler than with the Z 50mm f1.eight S wich has a way more variable gearing. The Z Noct is guide focus solely. The Z 50mm f1.2 S just like the Z Noct additionally has an additional button on the lens which will be assigned many alternative features e.g. AF-lock. [+]
Show: The Nikon Z 50mm f1.2 S options the identical OLED show because the Z Noct indicating aperture or focusing distance (in m or ft.) and depth-of-field. This show is tough to learn beneath sunny circumstances in its default setting however it may be made as vibrant as the highest show on the Z7. You may change by the completely different show varieties utilizing the DISP-button. The Z 50mm f1.eight S has no such show. [+]
Lens profile: The brand new Z-Nikkor comes with a lens profile which will be managed from the digital camera. Vignette management affords the standard choices of Excessive, Regular, Low and Off. Diffraction compensation and Auto distortion management will be activated or deactivated. That’s the identical as with the Z Noct or Z 50mm f1.eight S. [+]
Covers full body/FX or smaller. Similar with the Z Noct and Z 50mm f1.eight S. [+]
Worth: 2436 EUR (incl. 16% VAT) / 2100 USD / 2300 GBP. The Z 50mm f1.eight S at the moment goes for 489 EUR / 500 USD / 400 GBP and the Z Noct prices a whopping 8500 EUR / 8000 USD / 8300 GBP. The value of the brand new lens is akin to Canon’s RF 50mm f1.2 L USM. 
The lens comes with a pouch that’s simply as flimsy because the pouch of the opposite Z lenses (apart from the Z Noct) and has no strings to drag it shut. So in case you put the lens in your bag it would simply slip out of its pouch and bang round unprotected. That is merely unacceptable for a lens costing north of 2000 EUR/USD. The lens hood is included and locks in place to keep away from unintentionally falling off plus it’s reversible for transport. 
Aperture ring: Just like the Z Noct the Z 50mm f1.2 S has a slim multi-function management ring behind the lens along with the devoted focus ring. The management ring will be assigned to function the aperture (which is the default), publicity compensation, or ISO sensitivity – or just switched off. The Z 50mm f1.eight S has no devoted focus ring however its broad operate ring robotically falls again to focusing when the lens is switched to MF. [+]
Sealing: sure, a rubber grommet on the lens-mount plus additional particular weather-sealing all through the development, similar to the Z Noct and Z 50mm f1.eight S. [+]
The rating within the “features-department” is 1[-]/6/7[+]. The brand new Nikon Z 50mm f1.2 S is extraordinarily lengthy and fairly heavy and comes with a not insubstantial asking worth. For that it affords a nifty characteristic set and a really vibrant focal ratio of f1.2 which gathers a bit over one cease extra mild than the Z 50mm f1.eight S.
The marketplace for massive aperture customary prime lenses is fairly crowded however if you need autofocus and Z-mount there’s solely Nikon’s Z 50mm f1.eight S as a substitute. However shooters of Nikon Z cameras may additionally use F-mount lenses on Nikon’s FTZ adapter – including one other 31mm in size and 133g in weight:
- Nikon affords two autofocus alternate options with a focal ratio of f1.4: the AF-S 50mm f1.4G from 2008 (400 EUR/USD/GBP) and the AF-S 58mm f1.4G from 2013 (1500 EUR/USD/GBP). Each lenses are a lot smaller and lighter than the Z 50mm f1.2 S.
- Sigma has the AF 50mm f1.Four DG HSM Artwork from 2014 for 700 EUR / 950 USD / 600 GBP. See my Sigma 50mm f1.Four Artwork overview the place it got here Extremely Beneficial. The Sigma Artwork can also be a giant and heavy lens though not as excessive because the Z 50mm f1.2 S. Nonetheless: mounting it on the FTZ adapter the Sigma Artwork has a diameter of 85mm, a size of 130mm and a weight of 950g (w/o lens hood).
- Tokina affords the Opera 50mm f1.Four FF from 2018 for 700 EUR / 850 USD / 839 GBP which is even longer and heavier than the Sigma nearly reaching the dimensions and weight of the Z 50mm f1.2 Noct whenever you embrace the FTZ adapter.
Focus accuracy and repeatability is crucial to constantly produce sharp pictures. Repeatability (the accuracy of concentrate on the identical topic after repeated focus-acquisition) of this lens is sweet however not nice (measured 97.6% in Reikan FoCal) with no outliers over a sequence of 40 pictures. There’s a little bit of focus variation whether or not the lens focuses from a better distance or from infinity however I didn’t encounter searching beneath the nicely lit test-conditions. The lens focuses in round 0.6 sec from infinity to 0.64m (1:10 magnification), a bit slower than the Z 50mm f1.eight S at 0.5 sec.
The main target ring is 49mm vast. Its floor is rubberized, turns very easily and may simply be operated with one finger. AF-operation of the lens is audible from the skin however not sufficient to disturb your seatmate in a theater. In the event you report video with the built-in microphone the AF-drive produces a whirring noise whenever you power the lens to focus quick e. g. through the use of the AF-ON button or guide focusing. In the event you use Full-time AF the digital camera reduces focus pace to a stage the place it emits no sound – except the lens is searching. That is clearly the loudest Z-Nikkor thus far. In the event you use the management ring on the lens to alter the aperture this works easily and with out noise in video mode.
As you pull focus, you’ll hardly discover any focus respiration: Once I adjusted the main target from infinity to 0.64m on the Nikon Z 50mm f1.2 S I measured a 1.5% improve in magnification. That is completely inconspicuous and will please videographers. The Z 50mm f1.eight S breathes -1%, the Z Noct a hefty +16%.
