Super Flagship Sailing Nikon Quan Huafu SLR D5 Image Quality Evaluation

IT 168 evaluates every Olympic year, which is almost the best stage for CN flagship products to compete. In the Olympic year, the flagship products of these two companies often raise countless topics. Nikon officially released its latest top flagship SLR camera Nikon D5 at the CES show earlier this year. From the perspective of functions and various upgrades, it is sincere and has bright spots. Among them, what surprised me personally was the latest focusing system on Nikon D5. Nikon has been silent for so many years, and finally came up with a focusing system that matches the word flagship.

Needless to say, let's take a look at the performance of Nikon D5.

Upgrade points:

1. For the first time, the pixel of this level of SLR has been raised to 20 million.

2.AE/AF continuously shoots and tracks about 65,438+02 photos per second, and the mirror bounces about 65,438+04 photos per second. A single continuous shooting can take up to 200 photos in RAW format.

3. In normal mode, the sensitivity range is already ISO 100- 102400, ranging from ISO50 to ISO 3280000, exceeding ISO 3 million.

4. The brand-new 153-point focusing system has stronger low-light working ability from the center to the focus, with the lowest reaching -4EV, and other focus points are also at -3EV level (equivalent to the top-level low-light working ability of each focus point at present).

5. Add 4K function to record 30P video for 3 minutes each time.

6. The touch screen function is realized for the first time on Quan Huafu SLR, and a 3.2-inch touch LCD screen with 2.36 million pixels is configured.

7. Provide dual XQD storage or dual CF storage.

Buying guide:

Here we will definitely not discuss whether this camera is worth buying, because this product represents Nikon's current highest level and is definitely worth buying. If I choose a camera for the first time, is it the flagship of C family or Nikon D5? Because I haven't contacted flagship machine of C family, I can only say that these two products have their own advantages.

Therefore, for friends who want to buy Nikon D5, there is only one question, when to buy it. It is inevitable that Nikon D5 is out of stock now. If it's not bad, buy it at buy buy. Some time ago, the preferential price obtained by our ET teacher through the rebate platform was about 47,500-47,800 yuan. If you want to start around 40 thousand, you have to wait another 4-5 months.

1 and Nikon D5 have little change in overall appearance.

No matter Canon or Nikon, the appearance of each flagship model has been basically finalized, especially since D4, and Nikon D5 is no exception, but the shape of the "red scarf" can still be clearly seen from the appearance.

▲ Standard accessories include battery, charger, shoulder strap, data cable, hot shoe cover, interface fixer and instruction manual.

Nikon D5 uses the same EN-EL 18a lithium battery as D4/D4s.

Nikon D5 shutter accessories added a separate ISO button to replace the previous mode button, which was placed at the original BKT button position on the right side of the top of the fuselage.

▲ Nikon D4s

▲ Nikon D5

▲ The back of Nikon D5 fuselage

▲ Nikon D4s fuselage back

Through the back pictures of Nikon D4s and Nikon D5, we can also see the subtle changes that the buttons can't be arranged. The main reason is that Nikon D5 has added a Fn3 button on the back of the fuselage compared with Nikon D4s, and the info button has moved to the right side of the fuselage.

2. Brand-new 20-megapixel sensor with extremely high resolution.

With the continuous improvement of pixels of display devices, the quality requirements for news photos are much higher than before. This time, Nikon D5 used a self-made 20.8 megapixel Quan Huafu sensor and EXPEED 5 image processor. The flagship SLR has officially entered the 20 million era, which also marks that the image quality of the flagship SLR camera has entered a new era. So what about the picture quality of this 20.8 megapixel? Next, we took a sample shot with a 50mm F 1.4G Nikon D5, and took a 100% enlarged screenshot of the center and edge of the picture for comparison:

As can be seen from the screenshot above, D5, as the flagship model, has a very sharp image quality at both the center and the edge. It can fully meet the needs of professional photographers for image quality.

3, the sensitivity value is more than 3 million.

In addition to the original maximum sensitivity of Nikon D5 reaching ISO 102400, its extended ISO has also reached an astonishing 3280000. Nikon cameras have always been known for their high-sensitivity image quality. D3S/D4/D4S/Df and other models have very strong high-sensitivity shooting ability. How high will D5 raise this ability?

Through the comparison of the above screenshots, we can see that D5 is really good at high sensitivity. The camera keeps a fairly good picture cleanliness below ISO 1600, but it can still be used in ISO 12800. Although there is no expected leap-forward improvement, the overall improvement is still obvious and worthy of recognition. Although there is no sensitivity of 3280000, its arrival directly increases the available sensitivity, and the improvement of high sensitivity increases the application range of this camera. For some special subjects, especially sports and ecological subjects, the improvement of image quality at ordinary sensitivity is beneficial for users to use higher shutter speed and capture wonderful moments that are difficult to capture with naked eyes or previous cameras.

4. The strongest Nikon focusing system helps the Olympics.

After the release of Nikon D5, it can be seen from various upgrades that the brand-new focusing system of Nikon D5 is the most eye-catching upgrade function. The 5 1 point focusing system of previous generations has been slightly inferior to the top focusing system of C family, so this upgrade of Nikon D5 is a beautiful turnaround, which also makes many Nikon users hooked up.

Nikon D5 adopted a 153-point focusing system (including 55 optional focus points) in this autofocus system, and the overall area of the focusing system increased by about 30% compared with the previous generation D4s. 153 focus points, 99 focus points are cross focus points, which can achieve more accurate focusing performance.

Therefore, in the actual use process, we can manually select the focus from 55 focus points, and then other focus points cannot be selected, which plays a role in assisting focusing.

Nikon D5' s focusing system has not only changed in quantity, but also enhanced a lot in the focusing part of dark light. Nikon has developed a brand-new multi-CAM 20000 autofocus sensor module for D5, that is, all focus points have the focusing ability under the brightness of -3 EV, and the central focus point has also achieved the focusing ability of -4 EV. At present, the flagship model of C family is the focusing ability of -3EV, which means that all the focusing points of Nikon D5 have reached the current top level in dark focusing.

Because of the sharp increase in the number of focus points, the number of focus points supported by F5.6-7. 1, F8 and the extended mode has changed. That is, 37 foci support F5.6-7. 1 aperture (17 optional /25 intersections) and 15 foci support F8 aperture (9 optional /5 intersections).

Finally, it is worth mentioning that Nikon D5 has added autofocus locking function (this function has also appeared on C's flagship new machine, and it seems to be the mainstream function in the future). The main function of this function is also to improve the focusing accuracy. When other objects pass between the subject and the camera, if you choose to delay when blocking the autofocus response, it will not affect the focus of the original subject. If you choose fast, if something else passes by, the focus will change quickly and then return to the original subject.

The stability of shooting focus is mainly to adjust the motion trajectory of the object being photographed. If it suddenly starts or stops, it can be unstable, and if the object moves at a uniform speed, it can be stable.

Nikon D5 also has a new practical small function, that is, it can automatically fine-tune AF parameters with live view. We know that there is no out-of-focus problem in live view, so Nikon D5 automatically corrects the optical view AF through live view AF, saying goodbye to the tedious process of manual adjustment with focus detection card.

Generally speaking, Nikon D5' s focusing system allows photographers to shoot all kinds of subjects with confidence. Together with D5 14 fps' continuous shooting ability, this year's Olympic Games has been completely achieved.
