D80
As the only product with more than 30 million pixels in the 35mm digital SLR camera, 0 has been the hottest topic in the field of digital imaging since its release. After careful and in-depth evaluation by IT 168, I even dare to assert Nikon.
D80
0 will be the hottest product in the next three to four years. Before it's too late, let's learn more about D800. The appearance changes greatly, but the feel remains the same!
When I first saw Nikon D800, I felt that its overall shape was not? Nikon? . Its sleek design in my opinion?
General regulations
? A lot. In response to this question, the author asked the designer why in an exclusive interview in Japan. The answer is: In fact, when designing this product, many photographers think that this design has changed a lot compared with the tough appearance before, but Nikon still regards it as the inheritance of Giorgetto's design concept, and thinks that D800 has not changed the design route of Nikon SLR camera's appearance. Perhaps this design evolution needs an adaptation process.
▲ Nikon D800 positive observation Nikon D800.

Going? Slimming? The little red line at the back is simple and prominent. Many people are called Nikon? Little red underwear? Became? Little red belt? Yes, sexier. At the same time, the handle
The hand-held camera feels very comfortable, and there is an obvious groove design inside, in order to make the hand-held camera stronger and safer to use. And the camera shoulder is compared with D700.
It has sunk a lot, as if to give users a better perspective. ▲ Nikon D800 front shoulder screen contrast previous work
D700
there will be no changes. Judging from the key design in front of the shoulder screen, the switch key and camera key are designed reasonably. After holding the camera, the index finger can easily use the on-off key and camera key. The red key next to it is called the video recording key, and the surrounding exposure compensation key inherits Nikon's consistent product design. ▲ Nikon D800 shoulder screen is on the mode dial of Nikon D800, and
D70
0? Clover? The design has been changed? Four-leaf clover design, the tendency of keys and fingers is very comfortable, and a BKT button is added. The function of this button is to adjust the surrounding increment. This key design is also very useful for users who shoot indoors or at night. At the same time, the shooting mode roller is designed to be fully enclosed, which avoids the situation that the roller is too small to cause the wrong dial. In my opinion, the D800 round throw feels better in appearance than the D70 in design.
0 is more professional. ▲ Nikon D800' s mode dial is located in the lower right corner of the left side of the fuselage? FX？ Icon, symbolizing that this Nikon D800 is a Nikon Quan Huafu product, and its gold design and black body are particularly conspicuous.
▲ Nikon Quan Huafu FX icon Nikon D800 has made a leap in the number of pixels. 36.3 million effective pixels became the first SLR camera with 24 million pixels higher than the previous generation, and it was also the first 35mm digital SLR camera with more than 30 million pixels.
▲ Nikon D800 has a 36-megapixel design. The D800 has a built-in
flashlight
Compared with Canon,
The 5D series has never had the function of built-in flash, so it can play the role of emergency light and flash, and it is still very practical. ▲ Built-in flash
For such a high-end or even professional-grade product, whether flash is needed or not, the author thinks that although professional photographers will believe in external flash more, the built-in flash has better expansibility in emergency and lighting creativity. When D800 has reached 100% field of vision, why don't we flash internally?
The back menu still continues the design style of the previous generation, but the texture of the buttons has been greatly improved, and the work is tough and responsive. And the back uses a 3.2-inch display with about 920,000 pixels. (Say a little more here, the use of menu keys has been greatly improved. After entering the menu, there is obvious color difference on the display screen, and the selected options will be designed with colored lights, so you can clearly see the selected options, which is very convenient to operate the menu. )
▲ Back to Menu Nikon D800 has added video shooting function, and D-MOVE is also a big selling point of D800. In the fuselage design of D700, this part is the metering rod, while D800 has been replaced by the camera and camera switching rod. And put the LV key here to realize one-button switching, which is convenient for users to operate the camera.
▲ Menu key design viewfinder is an important improvement of D800, and the visual field rate of D800 is increased from 95% of Nikon D700 to 100%. I believe all photographers know what 100% field of view means, which means that this is a professional-grade SLR, which means that any photographer can make a rigorous composition through the optical viewfinder. Compared with the closing lever of D700,

When the design of predecessors is more reasonable, it will not be worn out because it is too close to the edge. ▲ SD and CF design of viewfinder D800 is very loving for photographers. Before, only one CF card could be stored in the card slot of D700. previous

Dual card slot design, both card slots are CF cards, while the SD and CF design of D800 is convenient for users. Compared with D4 dual-slot CF and XQD, the versatility is greatly improved. However, the plastic shell is slightly insufficient. ▲ The data interface part of the dual-card slot design has not changed much compared with the previous D700, but compared with Nikon professional SLR, the external rubber sleeve of the interface is not very sealed, and dust is likely to enter after long-term use.

, can not be used with the previous generation D700, because D800 uses socket contact power supply mode, while the previous generation D700 uses contact power supply interface. And, in the battery,
The design of the sealing part is changed, and the external power supply can be directly opened and connected.
. ▲ The design of the battery and battery compartment is round, but the feel is still the same. The key layout inherits the design of the previous generation Nikon SLR. It seems that this button design will also be Nikon's future design. Let's take a good look at the expected connotation of Nikon D800.

Nikon
D80
0, everyone will expect it to have excellent resolution and detail performance. The appearance of D800 is not just a pixel battle of digital SLR cameras. Therefore, we tested the resolution and clarity of D800. In the test, D800 is equipped with AF-S 50mm F 1.4G to shoot ISO 12233 resolution target (4000 lines). The following are the test results: ▲ Nikon.
The best resolution of D800 I thought that D800 would have a good performance in resolution, but I didn't expect the score of imatest software to explode directly after running several times ... More than 5,000 points in Nima ... This is the highest score in the testing machine I have ever seen in IT 168 ... 5D2 is in the database of IT 168 (including 50/65438).
▲D800 visual optimum resolution (JPG straight out) ▲D800 visual optimum resolution (Raw to JPG) In terms of visual resolution, Nikon D800' s JPG straight out proofs have exceeded 4,000 lines in the horizontal direction, while the ISO 12233 resolution target in Raw format can no longer fully show the actual resolution effect of D800. What changes have you had in your mood after reading these data? Believe it or not, let's take a look at the real shooting effect of D800.
The score only represents the camera and

Whether the adaptability of the evaluation criteria is really clear depends on the actual shooting effect. It's like taking the college entrance examination only represents whether you are suitable for the exam, and working ability is another matter. We took this photo in the standard evaluation environment, using Nikon head display 50F 1.4G, and the shooting parameters were F8 aperture in A file and ISO 100 sensitivity. ▲ We actually filmed the scene, and then cut off local slices of 100% from six positions respectively. Let's look at the performance of these slices.
▲D800 sample 100% screenshot From the sample slice, D800 does have high sharpness, which is the consistent performance style of Nikon cameras. Because it has 36.3 million pixels, all local slices are enlarged, which we have never encountered before in evaluating cameras. For objects on the focal plane, the center and edge of the picture have good details and sharpness. I think this is the quality that a high pixel should have.

0 high sensitivity performance was generally used by photographers as a joke before.
General regulations
5D2 interpolation beat a group? D80
0 high sensitivity sample? As a result, I lied to someone Then D800 and D700.
In contrast, we can see that the D800 has a very good high-sensitivity performance even if it is as high as 36.3 million pixels. But practice is the only criterion for testing truth. Let me test it myself and know what D800 looks like. The following scenario is the standard sensitivity test environment of IT 168 evaluation room. We fixed the camera on the heavy one.
tripod
On the gear pan/tilt, the camera can still shoot the sensitivity effect of each gear. Then we cut a photo slice from the same position in the above picture, as shown in the red box, to see how sensitive the D800 is.
First of all, let's compare a group of JPG slices with long exposure noise reduction and high sensitivity noise reduction turned off.
From the slice, we can see that the picture quality of D800 is very good from ISO 50 to ISO 400. Sharpness, noise control, detail preservation and color cast resistance are impeccable. In ISO 800, the picture began to show obvious noise, but the image quality from ISO 800 to ISO 1600 can still meet the demand of high-quality output. Yes, look at ISO 1600 carefully, although the noise is obvious and there is a slight color cast. But the details are still well preserved, and the sharpness is not significantly reduced. Generally speaking, it's not bad.
When the sensitivity reached ISO 3200, the noise broke out first, the details decreased obviously, and the sharpness loss began to be serious. Although D800 puts the common sensitivity in ISO 100-6400, I think it is better to use less than ISO 3200. As for ISO 6400-25600, it is really limited to emergency use, because compared with ISO 3200, ISO 6400 started, and the image quality dropped significantly.
Then let's see if it would be better to convert the raw materials into JPG.
From the sensitivity slice taken in RAW format in the above picture, the author finds that there is no obvious difference between it and JPG direct output. Only the sensitivity is put after ISO 3200, and the color shift of the picture is slightly better. If you really only use ISO 100-ISO 1600, there is absolutely no need to pursue low noise and shoot in RAW format. RAW format shooting mainly plays a greater role in ensuring the amount of information in photos.
Combine, use
Nikon
If users of D800 are conservative and harsh on image quality, try to use ISO 800 or less. It doesn't hurt to use ISO 1600 occasionally. Above ISO 3200, I don't recommend it unless you have an emergency. For such a high pixel SLR, we should not expect too much from it. High sensitivity can't be compared with the reporter's machine, so although the D800' s high sensitivity performance is average, compared with the advantages brought by its high pixel, this achievement is quite good. ${PageNumber} collection

This is good news for photographers who want to shoot business portraits with D800.
In addition, the author has always found that the color of Nikon D800 is yellow in automatic white balance. Therefore, I suggest that users who require high white balance, such as Nikon D800, shoot studio portraits and try to use custom white balance.
