Lightweight high-quality portrait head Nikon Z 85mm f/1.8 review
Today we bring you the evaluation of Nikon Z 85mm f/1.8 S, a lightweight portrait lens. This is the sixth lens in the Nikon Z series and the third f/1.8 family lens. This lens has a small size, but the real shot quality is very good, it is a high-quality portrait lens.
Overview of 01 lens
This Nikon lens inherits the typical style of Nikon Z series lenses. The lens barrel is straight and slender, and the design is simple and full of metallic texture. The size of the lens is not large, and the weight of the lens is only 470g, which is very light with the Z series body.
Nikon Z7 and Nikon 85mm f/1.8
The most amazing thing about this lens is the image quality. 85mm is a typical “high-quality focal length”. In traditional optical design, classic optical designs such as Sonner, Double Gauss, Planar, etc. can all be used for the 85mm lens focal length. Going back to the Nikon lens, the image quality of this lens is very good. It can maintain a very good lens resolution from the full leaning to the reduced aperture to f/16, and it is also excellent from the center to the edge.
The optical characteristics of the lens are also excellent. Not only the out-of-focus imaging is soft, but the vignetting is relatively slight, and the dispersion is almost invisible. You can use a large aperture to create creatives without worrying about other factors.
In short, this lens is a quality portrait lens. The domestic price has not yet been announced, and the overseas price is equivalent to about 5,000 yuan. Although as an 85mm f/1.8, 5000 yuan is slightly more expensive, but the price of the lens is definitely worthy of the lens quality. If you are a Nikon Z series user and are keen on portrait shooting, this lens is not cheap, but it is definitely worth buying.
Introduction to the appearance of 02 lens
The appearance of this lens is very simple. The overall look is a straight cylindrical shape, plus the lens hood is also a round hood, so It looks unconventional. The lens filter diameter is 67mm, which is a very common filter diameter.
There are not many design elements of the lens. The lens has a large focusing ring made of metal and does not include a custom multi-function ring on the 24-70mm f/2.8. There is only one focus mode switch button on the lens and no other design.
The lens coating is a yellow-green coating common to modern lenses, with more green parts. The optical structure of this lens is 12 elements in 8 groups, equipped with two low-dispersion ED lenses and nano-crystal-coated lenses. The material configuration is quite luxurious. In addition, the lens adopts a 9-blade aperture design to ensure the soft spot of out-of-focus shooting.
This lens retains the consistent style of the Nikon Z series lens, simple and generous, the focus damping is smooth when used, and the manual focus ring feels very good. Since most modern micro-single lenses use electronic focusing rings, the focus feel of this Nikon lens is among the micro-single lenses, which is quite excellent.
03 lens quality test
Now let’s take a look at the objective image quality test of this lens. First look at the resolution test.
The aperture value of this lens is f/1.8-16, and when shooting, each aperture has a very good picture quality performance. In terms of center image quality, the image quality is already very good when the aperture is fully opened, and the best image quality starts at f/2.0 and continues until f/11, when the center image quality drops at f/16. In terms of edge image quality, the best image quality starts at f/4 and continues to f/11. At f/16, the edge image quality also drops.
The image quality and resolution of this lens is not limited by the shooting distance. When shooting at close range, it also has amazing sharpness performance. Therefore, when shooting portraits, it can display excellent detail resolution. With the shortest focusing distance of 0.38 meters and the magnification of 0.22 times, this lens can also shoot some still life.

If you want to use this lens To shoot people, with the Nikon Z7 body, you can get very powerful detail resolution, and there is no pressure to deal with fine commercial output.

This This lens uses a 9-blade aperture, and the out-of-focus performance is very soft. Even compared with some f/1.4 portrait lenses, the out-of-focus effect of this lens is also excellent.
The blur effect of this lens is quite good. With a 9-blade aperture, the out-of-focus spot shape is round and there is no obvious bilinearity. In actual outdoor shooting, the out-of-focus image of the lens is soft, unlike some previous 85mm f/1.8 The lens is stiff out of focus and is a very qualified “strong blur lens”.

flare, dispersion, vignetting and distortion
first come Look at the lens flare control, which mainly depends on the coating quality of the lens. Whether this lens is fully opened or retracted to f/16, the flare control is ideal, and there is no obvious ghost or flare. It shows that the coating quality of the lens is quite good.
Then there is the dispersion control of the lens. In the test, the lens is quite ideal for the control of purple dispersion, and almost no purple fringing appears in each shooting environment. But when shooting metallic high-gloss objects, there is a slight green edge, which starts to weaken at f/2.8 and disappears completely at f/4. Generally speaking, the intensity of the green border is not great, and it can be easily removed by the body correction or post software.
there is a slight lens Green edges, but very easy to remove
The vignetting control of the lens is also good. At f/1.8, the edge loss is about 1.5EV. For a f/1.8 large aperture lens, this vignetting control is Ideal. Shrink the aperture to f/2.8, and the vignetting is almost invisible.
Finally look at the lens distortion performance. Among all kinds of lenses, 85mm belongs to a focal length with very small distortion, and the same is true for this 85mm f/1.8. From the perspective of distortion, this lens does not need to consider the effects of distortion.
The lens distortion control is very good
04 lens samples and summary
The author has used this lens for a period of time, and the biggest feeling is two words : Easy to use!
The biggest advantage of this lens is its excellent resolution and good out-of-focus imaging. The lens has a very good sharpness performance when the aperture is fully opened, and when it is contracted to f/2.0, it enters the best shooting state. This lens is not a landscape lens, so we will not deliberately use a small aperture to shoot. Under a large aperture, the sharpness of the center of the lens is excellent. Although the edge quality is insufficient, it does not affect portrait creation.
The out-of-focus performance of the lens is not inferior to many f/1.4 professional lenses. One is that the lens flare is round and beautiful, and the other is that the out-of-focus image of the lens is quite soft. This means that this lens can take good blur photos, and the closest focusing distance of the lens is only 0.38m, and it can also take some daily still photos.
In terms of dispersion performance, the edge dispersion is almost invisible after in-camera correction, so we can safely use a large aperture for shooting. And with the nano-crystalline coating, the lens quality is still excellent when shooting against the light.
It can be said that this is a high-quality lightweight portrait lens. The only drawback is that the current price of 5,000 yuan is slightly higher. If the price drops, it will definitely be more value-added.
Finally, let’s take a look at more samples of this lens.
