Nikon's Z800mmf/6.3VRS lens, launched this year, is a highly portable 800mm telephoto lens with excellent optical performance. It is also a Z bayonet professional telephoto lens with the longest basic focal length currently on sale by Nikon. Recently, I got this "Love in Dream" from many ecological photographers. Next, please join me to experience this essential telephoto lens!
Nikon Z9+Nikol Z800mmf/6.3VRS, f/6.31/800SecISO5000 Let's first break down Nikon's naming rules for Nikon's lens. The focal length of Nikon's Z800mmf/6.3VRS is the longest one since Nikon has stepped into the era of Z bayonet micro single lens. f/6.3 means that the maximum aperture of this lens is 6.3. From the perspective of the aperture of the standard large ternary lens f/2.8, F/6.3 is about 2.5 stops smaller than the aperture light input, which may be a pity for new photographers, but the focal length of the telephoto lens is positively related to the aperture. In the 800 mm focal length segment, the aperture of f/6.3 can already present the image of the "air cutter".
Nikon Z9+Nikol Z800mmf/6.3VRS, f/6.31/2000SecISO4000 VR in the lens name means that Nikon has built VR anti shake in this lens, which can automatically detect the camera shake information in the shock absorption system of the Nichol lens, and continuously move inside the lens, aligning the optical axis with the camera imaging sensor, thus reducing the image blur. The effect of this system is equivalent to raising the shutter speed up to 4.5 gears, which helps photographers to achieve clear shooting when shooting moving scenes, landscapes with insufficient light, and handheld photography. The S and S-Line in the lens name are Nikon's high performance labels for its own professional lens, which is the identity symbol of the flagship lens and also the quality assurance that Nikon gives consumers confidence.
Before the official test, let's have a look at the "birth certificate" of Nichol Z800mmf/6.3VRS. The lens adopts 14 groups of 22 pieces of optical glass lens group structure. It includes three low dispersion ED lenses, one blue light high refraction SR lens and one Fresnel phase PF lens. Because of the PF lens, it can achieve lightweight lens and high mobility.
PF lens can use the diffraction phenomenon of light to provide high chromatic aberration compensation capability. Is it possible to achieve lightweight simply because of the use of PF (Fresnel phase) lenses? No, in order to meet the needs of real outdoor ecological photography with high performance and portability, Nikon ingeniously reduced the number of lens elements and realized the double reduction of size and weight. Because of this, the weight of Nichol Z800mmf/6.3VRS is 2385g, and the length of the mirror body is only 385mm. It can reduce the pressure on our body when we go out to shoot, and users can easily come to the estimated shooting destination to capture vivid spirits.
By the way, usually the center of gravity of the telephoto lens shifts due to the balance of volume, weight and optical quality. Nikon also considered this problem when designing this lens. The Nikol Z800mmf/6.3VRS lens changes the inertia weight by bringing the weight of the lens closer to the side of the lens body through excellent design, This allows you to easily stop the camera at the position you need when the lens swings left and right during panning, so as to achieve more stable and smooth shooting.
Let's take a closer look at the appearance design of the mirror body and the support foot stand of the integrated design. The Z800mmf/6.3VRS has a raised black and white color contrast design metal nameplate, which is marked with the "NIKKOR" and the full name of the lens. The mirror body directly explains the maximum aperture of the lens focus and the PhaseFresnelLens marked in bright yellow The yellow words indicate the remarkable characteristics of this lens. The gold ring on the outer ring of the front lens set is a design language inherited from the history of Nikon, which tells you the professional positioning of this lens.
The front section of Nikol Z800mmf/6.3VRS lens tube is covered with a wide range of anti-skid rubber layers, providing a more stable and comfortable grip. At the same time, each control area provides different design lines, bringing different touch, so that users can get a more convenient operation experience when focusing on shooting.
The Nichol Z800mmf/6.3VRS lens adopts an internal focusing design. The front L-Fn2 function button of the NIKKORS logo is configured with four L-Fn2 function buttons and one L-Fn function button. Users can design shooting functions according to their personal preferences. Behind the NIKKORS logo is a multi-functional control ring with metal knurling process. Users can assign different functions according to their shooting habits to achieve faster and more convenient operation during shooting. In the actual shooting, I set it as the aperture control ring, which can help me adjust the light inflow when facing the sky and land with different exposures when shooting with manual M gear. The focus ring is behind the multi-functional control ring. The black rubber material ensures good skid resistance and controllability. During focusing, the damping is moderate, smooth, and delicate. The focus ring is located in a moderate position and matched with the appropriate size. Obviously, the photographer's real use status is taken into account. Recently, in my actual shooting process, it has helped me adjust and focus precisely in a complex bush environment for many times.
Nickle Z800mmf/6.3VRS is equipped with the necessary strap ring and bracket for the telephoto lens. The accessories also include the lens strap, which is convenient for users to carry when they go out to shoot. Behind the lens bracket ring are the L-Fn2 multi-function button, the automatic A/manual M focusing switch paddle and the focusing limit paddle. The focusing limit paddle has two gears, FULL (∞ - 5m) and ∞ - 10m, which can help me quickly adjust the shooting content suitable for the current situation in the required environment.
Nikon Z9+Nikol Z800mmf/6.3VRS, f/6.31/2000SecISO4000 The next point is easy to be ignored. Generally, this kind of large aperture lens is not suitable for setting filters in front of the lens (multifunctional filters, which are suitable for real shooting). The Nikol Z800mmf/6.3VRS adopts the design of a rear filter near the bayonet tail lens set, which can be photographed with a 46mm size filter. The filter device adopts the design of tilting, rotating and locking, so you can easily complete the operation with one hand. Its front mirror set adopts fluorine coating, which can effectively reduce the adhesion of dust and dirt, and can be easily cleaned. In addition, the lens adopts a dust-proof and waterproof design, providing reliable protection for outdoor environment shooting.
After talking for so long, I haven't presented the overall packaging photo of Nichol Z800mmf/6.3VRS for you! In order to make it convenient for users to carry, it is equipped with a special lens bag, with sponge pads inside to fix the lens, which is well protected. In addition, in the actual use process, Nikon has also configured a lens hood with the number of HB-104. With a more convenient locking device, it can be installed and disassembled by one hand. The LC-K106 soft lens cover can effectively protect the front lens set.
Nickel Z800mmF6.3VRS actual test
Before officially starting the test, first look at the MTF curve under the maximum aperture officially marked by Nikon As a member of S-type lens, Nichol Z800mmf/6.3VRS has excellent optical quality. In addition to the use of Fresnel phase (PF) lenses to achieve miniaturization and lightweight, this lens also uses three low dispersion (ED) lenses and one blue high refraction (SR) lens, which effectively reduces the axial chromatic aberration, so it can achieve excellent high-resolution performance. Let's take a look at the resolution of this lens under different apertures.
The body uses a 45 megapixel full frame micro single camera Nikon Z9. During the test, the anti shake function of the fuselage is turned off, the A-gear aperture priority mode is used, the sensitivity is set to ISO4000 (you can also see how the noise control of Nikon Z9 works), and the RAW+JPEG format is used to record. The aperture changes step by step starting from f/6.3, and finally the image of the intercepted edge is magnified for comparison.

Example of actually taken pictures From the above comparison chart, we can see that the resolution performance of Nichol Z800mmf/6.3VRS lens is the best when the aperture is fully open. At f/8-f/16 aperture, the resolution performance is also very good without too much fluctuation. The resolution starts to decline at f/22 aperture, but even at the smallest f/32 aperture, the details of both the center and the edge of the lens are still very good, with high usability.
Nikol Z800mmf/6.3VRS lens dispersion suppression test
When facing high contrast objects, especially when shooting with a large aperture, the edges of highlighted parts are prone to appear green or purple outlines. Serious dispersion will cause color distortion, thus affecting the overall picture quality. Now let's see how the 800mm lens performs on dispersion suppression. We used ISO2000 as the benchmark, and the aperture gradually changed. We captured the center of the picture for dispersion comparison test.
Example Diagram of Lens Dispersion Suppression Test For the test of dispersion control, the white thin line on the vertical and horizontal axis is also a particularly suitable test object, but the nearest focusing distance of 5 meters adds a lot of difficulty to the test.
The above is the original picture in actual shooting
As we said just now, this lens uses three low dispersion lenses and one blue high refraction lens, so it can reduce the axial chromatic aberration. From the test photos, there is almost no purple edge at the maximum aperture of f/6.3. How about the actual shooting?

Example diagram of anti glare test for mobile phone flash As an ecological and aviation photography specialized lens with a long focal length, backlighting is unavoidable. This lens uses the market recognized nanocrystalline coating, and also optimizes the shape and position of the PF lens to significantly reduce glare. This lens has no obvious glare when its aperture is fully open, and its anti glare ability is excellent. When the aperture is shrunk to f/13, starlight will appear, and when the aperture is f/16, beautiful and regular starlight will appear.
The above test on this lens is only for reference. Please join me in looking at the actual sample shot by Xiao Bian.

The Nikol Z800mmf/6.3VRS lens has excellent focusing performance, which can easily lock high-speed flying birds with Nikon Z9's ultra high-speed continuous shooting. In addition, it is equipped with a stepping motor to realize silent shooting, and reduce the operation sound during focusing and video recording. This function is suitable for quiet occasions, such as shooting wild birds and other wild animals.
High speed focusing diagram The editor has always mentioned the high portability of the Nichol Z800mmf/6.3VRS lens. The optimized weight control and overall coordination performance of the lens body can easily achieve handheld photography. In the process of handheld panning, there will be no head weight and foot weight. It can accurately grasp the time point that needs to hover. Although the maximum aperture is only f/6.3, it can bring clear and bright pictures under good outdoor light in the daytime. When shooting birds flying at high speed, a higher shutter speed can be obtained by properly adjusting the sensitivity. With the high-speed continuous shooting performance of Nikon Z9, you can freeze a wonderful moment.
