Evaluation of Nikon APS-C Ace D7 100 by photographers.

I 1T68 evaluation opened the resume of Nikon digital SLR, there is always a legendary series there. Nikon D70 was born for photographers nine years ago. Since then, Nikon APS-C mid-range digital SLR series has been the love of photographers. After D70, D70s, D80, D90 and D7000 all become classics, can D7 100 continue its legend?

20 13 In February, Nikon released a brand-new digital SLR camera D7 100 in APS-C format, adding new members to this brilliant series. However, Nikon users are picky and nostalgic. D7000 still sells well. The appearance of Nikon D7 100 is more like the products forced by younger brothers D5200 and D3200 when the glorious fire of D90 has not faded. But is this really the case?

Nikon has fully entered the era of high pixels. D7 100 is for photographers.

Although the D300s has not been upgraded, it may not be upgraded again. Nikon products have reached the level of 24 million pixels (D4 is a product that does not need high pixels), and D7 100 has become the last member of the 24 million club. With the appearance of Nikon D7 100, it can be said that Nikon has fully entered the era of high pixels.

When Nikon D7/KOOC-0/00 was released, many people thought that Nikon D7/KOOC-0/00 had become a flagship product, but in my opinion, Nikon D7/KOOC-0/00 was still for photographers. When I wrote these words after the trial, I think Nikon D7 100 is a good choice for users who are ready to learn photography or go to the road of photography.

Appearance, moderate atmosphere, comfortable grip and quick control.

The appearance of Nikon D7 100 has no obvious change with D7000, but it is almost the same as that of D600. The fuselage will not be too big or too small. It can be said that for a lover like me, learning photography is perfect. D7 100 handle is wide and moderate. When the index finger is placed at the shutter position, the three fingers below can be placed on the handle without feeling hanging.

In terms of key layout, there are all kinds of keys, including double dial, double-layer mode dial, and independent keys with common functions. When using Nikon D7 100, you can basically change the common parameters by dialing the dial or pressing the button, which is the highest operating efficiency of digital cameras at present.

It is worth mentioning that Nikon D7 100 has an I key on the lower left of the back of the fuselage, and other common settings can also be found in it. This shortcut allows photographers like me to basically abandon the menu, and the operation efficiency is greatly improved again.

▲ In addition to independent key adjustment, there is also an I key commonly used.

The viewfinder of Nikon D7 100 is undoubtedly another bright spot. In the viewfinder display part, D7 100 adopts high-intensity, high-contrast and energy-saving organic light-emitting diode display elements, and the usual green words become more comfortable white. In addition, the viewfinder can also display grid lines, which is very convenient for composition in the process of shooting landscapes or buildings.

This magical viewfinder not only has a brighter viewfinder effect and a higher-end white font display, but also has a virtual checkpoint in the viewfinder, which also plays a certain role in vertical shooting.

▲ Virtual horizontal display in viewfinder.

D7 100 adopts a 3.2-inch10.229 million-dot LCD screen, and the display screen adopts RGBW arrangement to increase brightness. D7 100 LCD adopts integrated glass panel structure (equivalent to D4, D800 series and D600), which can reduce surface reflection and light loss.

The LCD screen of the previous D7000 is not an integrated structure, and the air gap between the glass and the panel will cause reflection on the surfaces of various parts, resulting in partial light loss. It can be said that the display screen of D7 100 is the best among Nikon digital SLR cameras. From the actual use, the author found that this kind of LCD screen can really enhance the confidence of the photographer and help the photographer find the feeling and fun of shooting. This is very important.

Nikon D7 100 has two SD card slots. Because D7 100 pixel is high, it is recommended that you choose an SD card above 8G. Two SD card slots can be set for space addition, synchronous backup, one for recording original data and one for recording JPG.

▲ Card slot and battery compartment of Nikon D7 100

Nikon D7 100 battery is the same as Nikon D600/D800 battery. After the author's actual test, about 800 pictures can be taken, which is not as long as expected. If it's a day's shooting, I believe a battery can still support it, but if it's a trip or shooting, I still suggest buying an extra battery is safer.

Summary of appearance and operation evaluation:

The overall appearance of Nikon D7 100 has not changed significantly, and the comfort remains the same. However, with the addition of many functions and configurations of D7 100, this mid-range SLR camera has a better user experience. The improvement of Nikon D7 100 in the use experience can only be realized if it has been used. It can be said that only the feet know whether the shoes are comfortable or not.

The picture quality is clear, but be careful of moire.

Nikon D7 100 uses a CMOS sensor with 2465438+ effective megapixels, which is the same as Nikon D5200, but D7 100 cancels the low-pass filter. At present, many digital cameras have cancelled the low-pass filter, and it has become a trend to go low-pass. D7 100 without the low-pass filter really further improves the resolution. For high-pixel SLR cameras, removing the low-pass filter can obviously highlight the advantages of shooting clarity.

▲ Using the same sensor, compared with D5200 on the left, the CMOS of D7 100 on the right cancels the low-pass filter.

Let's look at the actual sample first. In the picture below, I cut off 100% of the original slice of the swan's head and body:

As can be seen from the above picture, Nikon D7 100 without low-pass filter really shows good detail expression in actual shooting. 2,465,438+10,000 effective pixels are perfectly displayed in HD. The water on the feather and the details of the feather are very clear.

In the evaluation room, the author tested the resolution of Nikon D7 100. Through ISO 12233 standard test, it is not difficult to find that D7 100 without low-pass filter has obvious progress compared with D5200. From the objective evaluation in the laboratory, we do come to the conclusion that D7 100 has a good performance in resolution after removing the low-pass filter.

▲ The resolution comparison between D7100 and D5200.

However, removing the low-pass filter also means that moire fringes may appear. According to the author's practical experience, Nikon D7 100 has higher probability of moire than Fuji X-E 1, Nikon D800E and Nikon V2. It is also strange to the author why D7 100 does not perform well in removing low pass. When using D7 100, it is recommended to avoid shooting textures.

The above picture is a lab test sample. We can clearly see the moire fringe from the dollar screenshot, which did not appear when using Fuji X-Trans sensor and Nikon D800E to test the camera.

Resolution evaluation summary:

Nikon D7 100 has the top resolution in APS-C format digital SLR, and the photos taken are rich in details and good in definition. However, moire fringes are also used when shooting textured objects. However, the author thinks that we can't give up eating because of choking, and choosing the angle can also avoid the appearance of moire fringe, and the resolution is what users who buy high-pixel cameras pursue.

High-sensitivity performance is the sorrow of ordinary high-pixel cameras.

High pixels can bring good definition, but at the same time, high pixels per inch can also cause poor high-sensitivity performance. High sensitivity performance is very helpful for night scenes and indoor photography. Unfortunately, Nikon D7 100 obviously does not show a good advantage in high sensitivity because of its high pixels.

▲ Sensitivity test area

Like D5200 and D3200, D7 100 can still have a good picture quality in ISO 800, and once it exceeds ISO 1600, it has obvious graininess. High pixel and high sensory performance are the relationship between fish and bear's paw. How to choose depends on everyone.

▲ Nikon D7 100 High Sensitivity Test

Compared with Nikon D5200 and D3200, Nikon D7 100 is at the same level. If photography enthusiasts choose ASP-C digital SLR camera, I will definitely recommend D7 100, but if the budget can be more, maybe D600 is also a good choice.

Let's take a look at the comparison between Nikon D7 100 and D600:

From the comparison, we can easily see that Nikon D600' s high sensitivity performance is better than D7 100. In ISO 1600, the Nikon D600 screen is still exquisite.

Summary of high sensitivity evaluation:

The high sensitivity performance of D7 100 had an expectation in my heart before I got the camera. At present, the high sensitivity level of almost all 24-megapixel APS-C format cameras stays at the ISO 800 usable line. So, if you want to find a digital SLR camera with better performance, you should either choose a camera with lower pixels or choose a SLR from Quan Huafu.

So I think fans who really value camera pixels should not care about high-sensitivity performance, or photographers with spare money can choose Nikon D600.

1.3 times cutting is more practical for moving point white balance.

The cutting mode of Nikon D7 100 is 1.3 times. In this mode, the equivalent focal length can be twice the actual focal length, and the continuous shooting speed can be increased to 7 frames per second. What's more noteworthy is that in the cropping mode of 1.3 times, the focus of Nikon D7 100 covers almost the whole framing space. This configuration is simply born for shooting sports, and sports photographers and birdwatchers can say that they have new artifacts.

Of course, for ordinary lovers, shooting birds and shooting sports photography may not be the daily shooting theme. But the sun rises every day, and sunrise and sunset are also good subjects for telephoto shooting. The picture below was taken on my way to work one day. Nikon D7 100 can obtain the equivalent effects of 600mm and 800mm( 1.3 times cutting mode) when shooting with the 400mm end of the AD-S 80-400G lens.

▲ Super telephoto always brings unusual effects.

800mm can bring many different things to lovers. I often say, generally speaking, no focal length, which subject should be shot, but super telephoto can really bring many new experiences when shooting.

▲ 7 continuous shooting effects per second.

Although the cropping of 1.3 times can be completed in the later stage, in practical use, the feeling of composition and the focus of the whole picture contribute to better shooting. I think this function is practical, and the continuous shooting speed can be increased to 7 frames per second. What can I do with 7 cards per second? Look at the picture and you will know.

For sports photographers or birdwatchers who use telephoto lenses, it is cumbersome to preset white balance in complex light, and the white balance function of D7 100 is undoubtedly more practical. The photographer can set the white balance according to the object or part of the object selected during live view. You can use multiple selectors to set the point white balance anywhere.

It has been said before that the focus of Nikon D7 100 can cover the whole picture in the cropping mode of 1.3 times, which shows that the focus area of Nikon D7 100 is large, and on the other hand, Nikon D7 100 has many focal points. Nikon D7 100 has a focus of 5 1, which surpasses D7000 and D600, so it is very sincere.

▲ 15 cross focus (f/5.6); The central intersection is compatible with f/8.0.

▲ 1.3 times cropping almost completely covers the focus.

Nikon claims that the auto-focus detection limit of the focusing system of D7 100 reaches -2EV(ISO 100, 2020? C/68？ F), which is better than D600(- 1EV). However, in terms of supporting f/8 aperture autofocus function, D7 100 only supports the center point (cross), which is not as good as D600 in quantity. But for photographers, Nikon D7 100 focusing system can even be said to be a luxury.

Summary of function and performance evaluation:

As far as the overall function of Nikon D7 100 is concerned, it has not shrunk at all compared with the previous work, but its practical function and operability are by going up one flight of stairs. As a photographer, I think this is one that can realize almost all your photography dreams? First love? .

Evaluation summary: D7 100 can be the first partner to help you get into photography.

The control is simple and fast, the practical functions are improved a lot, and the picture quality is outstanding. Nikon D7 100 is the ace digital SLR in APS-C. The reason why I didn't use the word "flagship" is because the rigidity of the fuselage is different from that of flagship machine D300s n years ago, and the continuous shooting speed under full pixel output can't reach 8 frames per second. This continuous shooting speed is the continuous shooting speed of Canon EOS 7D.

However, as early as the release of D7000, the author thought that D7000 had surpassed D300s to some extent, and was more worthy of recommendation than D300s. Now D7 100 says it is normal to surpass D300s in an all-round way. I don't know if there is a flagship machine like D400, but it is absolutely no exaggeration to say that D7 100 is the trump card of Nikon APS-C digital SLR at present.

With the development of video culture, more and more promising young people hope to carry their dreams and cultivate their sentiments through photography. Choosing your first SLR camera is like choosing a loyal partner. Again, Nikon D7 100 is for photographers, and it will definitely become the most reliable partner on the road of learning photography.

Advice to photographers

I bought Nikon D70 and AF-S 18-70 G DX in 2004 and started my photography dream. In my opinion, Nikon APS-C mid-range digital SLR can help enthusiasts start their photography journey. So when D7 100 is sent for testing, I will have more feelings in my heart.

At present, Nikon digital SLR has been popularized in Quan Huafu. For photographers, I recommend two products, one is D7 100 in this evaluation, and the other is Nikon Quan Huafu SLR D600. These two products can meet the needs of photographers to learn photography in terms of overall image quality, performance and function, and they are not too expensive.

The overall performance of the two products is similar, and the D600 is Quan Huafu's advantage in lens equipment and image quality. If the budget is sufficient, it is recommended to enter the full map threshold. If the budget is limited, D7 100 will surely carry your photography dream.

If users buy D7 100, I recommend buying D7 100 with AF-S 18-35G. On the one hand, on the D7 100 of APS-C format, 18-35mm can be equivalent to a standard zoom lens of 27-52.2mm, and this lens is a Quan Huafu super wide-angle lens, which can still be used when it is upgraded to Quan Huafu fuselage in the future. At present, the price of AF-S 18-35G lens is nearly 5000 yuan, which is not expensive. Please click to view the latest quotation.

However, I suggest you take the money and wait and see for a while. If you have any questions about the purchase of Nikon D7 100 and glasses, you can send them to Weibo.
