The Nikon Nikkor Z 50mm F1.2 S ($ 2199.95) is a big bonus objective with an exotic aperture f / 1.2. When shot wide open, it networks photos with more blurry backgrounds than what you'll get with Nikon's other standard premium, Nikkor Z 50 mm F1.8 S . It takes massive optics to get there, and while it saves its weight with crisp images, it's a niche lens for photographers who want photos with the lowest depth of field and want to work in. the lowest light.
An imposing lens
As a general rule, lenses that collect more light use larger, heavier glass elements. The Nikkor Z 50mm F1.2 S is no exception. It's big for a premium, at 5.9 by 3.5 inches (HD), and heavier than your camera, at 2.4 pounds. It's a bit bigger than Canon's RF 50mm F1.2 L USM (4.3 by 3.5in, 2.1lb), but not dramatically.
The Z 50mm supports 82mm front filters and comes with front and rear lens caps. A hood is also included; it locks with a bayonet mount and is reversible for storage and transport. Everything is finished in matte black and internal gaskets protect from dust and splash. Nikon does not include fluorine or other form of protection anti-stain on the glass, which is disappointing considering the fit and fpremium inition.
Nikon has a brighter lens in its catalog, the Nikkor Z 58mm F0. 95 S Noct, it 's only manual focus, but the 50mm F1.2 supports autofocus. It's not super fast: going from a close focus to a distant subject takes about half a second on the Z 7 II .

Manual focus is also available. The focus ring takes up most of the area. It is rubberized, with ridges for maximum comfortable grip. It rotates easily, but does not offer a linear response. This means that the focus changes more drastically when you turn thebarrel quickly, while slower turns make smaller adjustments.
The ring turns a little too easily for my taste; I would like to see a little more resistance for fine tuning. I like the ramp response for photography - especially for making very tiny changes - but videographers generally look for a linear focus response, one that allows for repeatable racks to keep things consistent from one angle to the next. taken to another.
An AF / MF toggle switch quickly changes the focus mode and permanent manual focus is available - just turn the ring. It is joined by two buttons, the Lens Function button (L-Fn) is customizable and Disp changes what is displayed on the OLED information panel of the lens.It can be set to display aperture, set focal length, or disabled.
There is a second control ring, closer to the base of the lens. It can be set to adjust EV, aperture, or ISO, but this is a command I usually turn off on Z cameras. The ring rotates very easily, enough that you are likely to adjust the settings by accident. .

Focus is available at 17.7 inch (0.45m), good enough for full-size magnification of 1: 6.7 at closest working distance. It matches other fast 50mm lenses - it roughly matches the Nikkor Z 50mm F1.8 S. There is virtually no change in angle of view when the focus is adjusted, useful for video shots with a change in the focal plane.
Image stabilization is not included, but neither is it. Z camerasfull frame that most will associate the lens with include a five-axis IBIS It's good enough for me to get consistently blur-free images at pocket speeds as long as 1/4 of a second with the Z 7 II.
In the lab
To evaluate this solution, I tested the Nikkor Z 50mm F1.2 S with the 45MP Z 7 II and the software of Imatest .

At the larger f / 1.2 aperture, the pair capture images that offer good resolution (3400 lines). There is some lost resolution at the edges on our focus graph. point to flat field, but this is an academic concern - when creating images at f / 1.2, the periphery of your images is likely to be blurry.
Cis one of those lenses that gets sharper as the aperture narrows. At f / 1.4, it increases a bit (3525 lines) and offers almost excellent resolution initially at f / 2 (3930 lines). At f / 2.8 and above, it's better (4,500 lines), and it offers exceptional clarity at f / 4 and f / 5.6 (4,800 lines).
There is a modest drop in clarity at f / 8 and f / 11, but diffraction doesn't really show its effects until you set the lens to its smallest aperture of f / 16, and even then it still delivers very solid results (3900 lines).

The resolution doesn 't is not all, but if you put a priority on wide open clarity, know that the Nikkor Z 50mm F1.8 S is a bit better when it isis shot at f / 1.8 (4375 lines), and isn 't that far when stopped (4540 lines at f /4).

The Nikkor Z 50mm F1. 2S shows almost no distortion, even if you turn off the in-camera corrections. It relies on some assistance to correct a vignette - corners and edges are noticeably darker at the edges at f / 1, 2 and f / 1.4 without them. When on, you get a nice natural vignette at f / 1.2, a vignette more subtle than distracting.
The bokeh, the quality of the area defocused of an image, is important in a fast lens. The 50mm F1.2 draws perfectly smooth backgrounds when taken wide open, and uses a nine-blade aperture to keep defocused reflections circular when it is stopped.

When the The lens is wide open, the defocused highlights are circular towards the center, but take the shape of a cat's eye towards the edges of the aperture. The narrowing of the aperture helps to highlight circular highlights all over the frame.
Exotic glass doesn't disappoint
The Nikkor Z 50mm F1.2 S joins the growing ranks of big lenses for mirrorless cameras, but it's not heavy for no reason. The lens collects more light than common 50mm F1.4 models when taken wide open, and it delivers images with a high contrast and clarity. From an optical point of view, it is a realization.
Should you l 'buy? If you don't mind the cost or the size, please be glad to know the pictures it createde are quite fantastic. From a handling point of view, it's definitely a bit heavy up front and can take a while to focus. You won't complain about the results, however, or the ability to shoot with a depth of field as thin as hair.
If this is your cup of tea, the 50mm F1.2 S is a good fit. But we will continue to recommend the Nikkor Z 50mm F1.8 S a little more to most photographers. He is an amazing artist in his own right and costs only $ 600. You lose the exotic appeal of F1.2 glass, but the 50mm F1.8 S is a smarter choice, and our editors' choice winner.
