Nikon continues to implement the principle of maximizing the f/1.8 series lens in its mirrorless Z system, so it currently has four prime lenses including 24mm, 35mm, 50mm, and 85mm. Under the premise of miniaturization of mirrorless products, the practical aperture and price are measured. This idea also continues the essence of the f/1.8 series fixed focus lens widely recognized by Nikon in the F series SLR products. The lens tested this time, the NIKKOR Z24mmf/1.8S lens, is currently the widest focal length among Nikon Z series fixed focal length products, and it is also a brand new product recently launched.
From the shooting scene, the main application of 24mm lens The scenes are architecture, scenery, indoor environment, etc. And this lens with f/1.8 maximum aperture gives this product more subjects and possibilities for shooting in dark light or night scenes. Therefore, as a large-aperture wide-angle lens, what we want to focus on is the resolution performance of this product from center to edge, as well as vignetting and distortion and other key factors that affect landscape or architectural photography.

NIKKOR Z24mmf/1.8S adopts an optical design of 12 elements in 10 groups, including 1 low-dispersion ED lens and 4 aspherical lenses to provide excellent optical performance. In addition, Nikon’s coating technology Nano Crystal Coat effectively reduces ghosting and flare caused by incident light. The body used in this evaluation is a Nikon Z7, and all photos are taken in NEF format and converted to JPG format. The current official price of the NIKKOR Z24mmf/1.8S lens is 7180 yuan, which is a great tool to strengthen the wide-angle end of the Nikon Z series.
The appearance continues the black style of the Z series lens
NIKKOR Z24mmf/1.8S lens continues the characteristics of the Z series lens. Whether it’s the yellow and black color packaging or the all-in-one lens body, it looks exceptionally simple.

Although is a wide-angle lens, this lens does not have the rough caliber of previous wide-angle lenses in appearance, 72mm The filter caliber of this lens makes this lens look slimmer overall, and the weight of about 450g will definitely not become a burden when you go out. In fact, the 72mm aperture is considered to be the largest among the four current f/1.8 series lens products, but for a product with 24mm+f/1.8 optical specifications, it is still small and flexible.

After is matched with Z6 body, the advantage of the lightweight lens , The overall center of gravity of the grip is good, and there is no forward “nodding” after installation. This is more convenient for stability when using wide-angle handheld shooting some slow shutter scenes. Let me take a look at the highlights of this new wide-angle and large-aperture lens through the evaluation below.
Resolution real shot: excellent center image quality
In the resolution real shot, you can examine the real resolution performance of this lens from center to edge. Here I fixed the camera position, and adjusted the aperture step by step to shoot, intercepting the center and edge image quality for the following display.
From the actual shooting results, NIKKOR Z24mmf/ The center image quality of the 1.8S lens can always be maintained excellent, even at full f/1.8 aperture, the resolution is also very high. The full-open image quality of the edge is a bit weak, but the edge image quality after shrinking to f/4.0 has been improved. From the gradual change of the aperture, it can also be seen that there will be vignetting under the maximum aperture. Therefore, when shooting large scenes such as scenery, it is recommended to use an aperture of f/4.0 or smaller to obtain the best image quality.
Blurring and vignetting performance of each stop aperture
Although the blurring effect of the wide-angle lens is not its key advantage, it is a product with f/1.8 aperture index , Its out-of-focus performance is still worthy of our attention. Similarly, I fixed the camera position, set the focus ring to the closest focusing distance, and tested the blur performance under different apertures step by step.

From the perspective of the blur effect of the maximum aperture , The NIKKOR Z24mmf/1.8S lens can obtain a brilliant round spot in the center, while a certain aperture erosion phenomenon appears at the edge, which is a normal optical phenomenon for a wide-angle large-aperture lens. Although the overall blurring atmosphere is not comparable to longer focal length lenses, when shooting close-up scenes, it is enough to achieve a charming atmosphere effect that contrasts the subject, which is also reflected in the sample at the end of the article. The following will test the performance of the vignetting.
actually used to be Vignetting can already be seen in the resolution test, but this is not serious for a wide-angle lens. After turning off the optimization options for vignetting in the camera, you can see that there will be more obvious vignetting on the edge of the picture under f/1.8-f/2.8, and when the aperture is reduced to f/4.0 or less, the vignetting The situation improved immediately. When aiming at blue sky or pure color scenes, pay special attention to the effect of vignetting on the picture.
distortion, dispersion and starburst effect test
For a wide-angle lens, distortion is one of the aspects that most affect the visual effect of imaging, so I am also interested in this, NIKKOR Z24mmf/ The 1.8S lens has undergone a simple distortion test to observe its distortion at different focusing distances. The pictures below are pictures taken at 1 meter and 3 meters. The distortion can be seen from the line from the center to the edge of the picture. The ability to control.

Through observation, it can be found that the distortion performance of the NIKKOR Z24mmf/1.8S lens is acceptable, although there are noticeable barrel distortions at different shooting distances , But also limited to the edges, and the lines in the center of the picture can still be horizontal and vertical. Then, with the dispersion-related internal optimization turned off in the camera, I looked for two extremely strong highlight scenes to observe the dispersion performance of this lens. The following is a screenshot of the highlight area.
the direct rays of the sun The highlight produced by the reflection of metal is the “killer” of many lenses. By observing the real shots of the NIKKOR Z24mmf/1.8S lens, this lens will have a slight purple fringing at the full aperture in very extreme situations, but in most cases there will be almost no dispersion.
Astral effect is a big factor that many users fancy wide-angle lenses. The perfect starburst effect will bring a different vivid atmosphere to some night scenes. The astral performance test of this NIKKOR Z24mmf/1.8S lens is as follows.
Focal length: 24mm Aperture: f/11.0 ISO sensitivity: 100 Exposure time: 1/50s Exposure compensation: 0EV White balance: Automatic
Through the observation of the starburst, it is not difficult to see that the astral performance of this lens is unique. A significant starburst effect can appear starting from f/5.6. The starburst under f/16 aperture is more sharp and dazzling, and the remarkable starburst effect will bring more visual impact to the picture. In the face of such strong light, the NIKKOR Z24mmf/1.8S lens did not show obvious glare, which shows that the overall quality of this lens is very high.
Sample display and summary
When shooting samples, I tried my best to show the performance of this lens in different scenarios. Here, I shot a variety of different subjects such as architecture, portraits, and still lifes. I also tried to shoot at close range and under low light. The following is a display of real photos, and only the white balance was adjusted in the later stage.

For a wide-angle and large-aperture lens like the NIKKOR Z24mmf/1.8S lens, after these few days The use of I found that there are still many challenges in shooting, such as the need for more rigorous composition or consideration of light, but it can indeed expand the subject matter of shooting. In terms of image quality, the quality of this lens is naturally beyond doubt. In addition to continuing the accustomed sharp image texture of Nikon Z series lenses, the large aperture of f/1.8 makes the wide-angle image also have a charming out-of-focus blur. On the whole, the NIKKOR Z24mmf/1.8S lens can be controlled in architecture, scenery, portraits, and even humanities and still life subjects. It is a high-quality lens that is worthy of being “deeply explored”.
