Fixed focus wide-angle sharp edge NIKKOR Z 20mm f/1.8 S review

  This article is from Hummingbird.

   I recently got a brand new large aperture prime lens, that is the Nikkor Z20mmf/1.8S prime lens. Not long ago, I just met Nikon’s own Nick Z70-200mmf/2.8VRS was evaluated. The NIKKOR Z20mmf/1.8S is a high-quality wide-angle fixed focus lens following the NIKKOR Z70-200mmf/2.8VRS telephoto lens. As Nikon’s own S-Line lens, it will naturally have enough confidence in imaging, especially For large diameter, short flange distance fixed focus wide angle, this can be said to be an inherent advantage.

   NIKKOR Z20mmf/1.8S

   NIKKOR’s setting in Z20mmf/1.8S The large-aperture wide-angle lens incorporates many advanced optical technologies from Nikon, uses multiple low-dispersion lenses, and does a great job in wide-angle correction. What kind of dazzling performance this lens will bring to us, we need to pass actual shooting evaluation before we can reach a conclusion.

  appearance and detail analysis

  In terms of appearance, I got this NIKKOR Z20mmf/1.8S. I was surprised by the size of this lens. Compared with the 20mm fixed focal length lenses currently on the market, this NIKKOR Z20mmf/1.8S is considered to be relatively large. Of course, although this lens is larger in size, in order to reduce the axial chromatic aberration of the lens, the NIKKOR Z20mmf/1.8S uses 3 low-dispersion glass lenses, which enables this lens to cover the entire shooting range from close to infinity. Effectively compensate for axial chromatic aberration and provide clear resolution. As a lens mainly used for shooting scenery, it will definitely work hard in anti-glare and ghosting. The NIKKOR Z20mmf/1.8S lens adopts nano crystal coating, which can effectively reduce the interference in wide-angle landscape photos. The influence of ghosts and glare caused by the sun, which we will see in the actual test later.

   Of course, in addition to what I said before, the NIKKOR Z20mmf/1.8S uses 3 low-dispersion glass lenses and nano crystal coating, but also uses Three aspherical lenses can effectively compensate aberrations to a certain extent. After talking about the “lining” of this NIKKOR Z20mmf/1.8S lens, let’s talk about the “face” of this lens.

   NIKKOR Z20mmf/1.8S is still very simple in appearance design, and the overall lens feel is a very delicate matte texture, especially focusing The damping feel of the ring is also very delicate. Due to the volume factor of this lens, the focus ring is relatively wider, which also makes for a better operating experience when shooting.

  Nikkor Z20mmf/1.8S details

  The whole lens is finished, let’s talk about the details of this lens. The design of this lens can be said to be simple to the extreme. The “NIKKOR” logo and the lens focal length and aperture information are marked on the front of the lens. The rear part echoes the choice of lens focus mode, and the “NIKKORS nameplate” highlights this. The origin of this lens is Nikon S-Line series lens.

  Although the volume of this lens is slightly larger, when this lens is equipped with the Nikon Z7, the hand feels less Doesn’t feel any pressure, but adds a bit of holding stability. As the saying goes, Lu Yao knows the horsepower, no matter how good the stacking parameters of the lens are, you still have to go through the actual shooting to see the true ability. Next, we will enter the real evaluation and real shooting.

  lens resolution test

   NIKKOR S-Line series lenses have always been synonymous with excellent image quality. In this series, Nikon The lens materials and technology investment are absolutely unambiguous, so what kind of performance will the NIKKOR Z20mmf/1.8S lens have in terms of image quality? Let’s take a look at it. The body used in this test is Nikon. Z7. In the real shot resolution test, we tested the gradual aperture of the NIKKOR Z20mmf/1.8S lens, and performed 100% screenshot observation of the center and edge positions of the shooting picture.

   NIKKOR Z20mmf/1.8S resolution test

   From the actual shooting results, the NIKKOR Z20mmf/1.8 resolution test performance is basically amazing To describe it. When the aperture is fully opened, the center of the NIKKOR Z20mmf/1.8S picture is very sharp, even when the aperture is reduced to the smallest aperture f/16 that is rarely used in daily life, it also has a very brilliant sharpness performance. The resolution performance of the NIKKOR Z20mmf/1.8S lens is definitely on the top level.

  Background blur real shot

  Although the NIKKOR Z20mmf/1.8 is a fixed-focus wide-angle lens, it will not give the actual focal length The shooting brings a significant depth of field experience, but don’t forget that this is also a large-aperture lens with many special lenses. I believe this lens should have an excellent performance in background blur.

   From the real shot performance of NIKKOR Z20mmf/1.8S background blur, Regardless of the center position or the edge position of the picture, the out-of-focus light spot presents an unconventional round shape without obvious aperture erosion. In addition, the edge transition of the light spot is also very clean and there is no onion ring phenomenon.

  Vignette and distortion real shot

  Vignette size is also a measure of the overall quality of a lens One of the important factors. Although in the digital age is not the only criterion to consider the lens, and it can be perfectly removed through in-camera optimization, I think it is still necessary to take a look at this lens when the in-camera correction is turned off. The performance of the lens.

  Maximum aperture Vignetting performance

   From the actual shooting point of view, the NIKKOR Z20mmf/1.8 lens does have a relatively obvious vignetting at the maximum aperture, but with the aperture The vignetting situation has also been significantly improved due to the shrinkage of the camera, and the Nikon Z7 machine provides a 3-stop vignetting optimization, so the lens vignetting problem can be improved by the camera’s own optimization.

Distortion test at a distance of about 3 meters

   During the distortion test, I photographed a brick wall with grid characteristics for reference. It is known that it is easy to produce when shooting at wide-angle end. Barrel distortion, especially in wide-angle close-up shooting, this situation will be more obvious. Through the real shots above, it can be seen that even if the NIKKOR Z20mmf/1.8S lens is closed for camera correction, the distortion is almost imperceptible when shooting relatively sharp walls at close range.

  Dispersion and anti-glare test

  Shooting scenery encounters backlight and high light ratio environment It can be said to be commonplace, especially for a fixed focal wide-angle lens. Earlier in the article, we said that the NIKKOR Z20mmf/1.8S uses 3 low-dispersion glass lenses, and the entire shooting range from close to infinity can effectively compensate for axial chromatic aberration. In the actual shooting process, the anti-dispersion performance of the NIKKOR Z20mmf/1.8S is indeed very good.

  From the actual shooting results, the NIKKOR Z20mmf/1.8S does perform well in the control of dispersion, some of which are out of focus The slight purple fringing and green fringing are what we call axial dispersion.

   glare test

   uses NIKKOR Z20mmf/1.8S to shoot directly at direct strong light, and when the aperture is fully opened, NIKKOR Z20mmf/1.8S does not Obvious glare phenomenon, such a result is inseparable from the nano crystal coating used in this lens.

  Real shot samples and editorial summary

   Although the volume of this lens is slightly larger than similar products, it is actually I seem to have overlooked the size and weight of this lens during shooting, and basically it will not put pressure on the handheld during shooting. If the size of the NIKKOR Z20mmf/1.8S lens must be counted as a flaw, then it can be said that the excellent image quality performance of this lens is “not concealed”.
