Evaluation of the New Classic Nikon D850 SLR Camera with a Hundred Years' History

IT 168 evaluation 20 17 is the centenary of Nikon's birth. As a "century-old gift machine", D850 has attracted a lot of attention before it went on the market. On the one hand, everyone cares about the machine itself and wants to know how many surprises it can bring us; On the one hand, everyone cares about Nikon. In the case of market downturn and unfavorable years (flood in Thailand and Kumamoto earthquake), we really need a product that is hard-driven enough to give Nikon a shot in the arm.

45.75 million pixels without low-pass sensor, 153-point focusing system, with a maximum continuous shooting of 9 frames per second. Since no SLR camera can achieve high pixel and high-speed continuous shooting at the same time before, the D850 has given people an unprecedented shock as soon as it was released.

"In the digital age, there has never been such a sincere SLR camera"-a veteran commented on the D850.

What kind of intuitive experience can we get from the great strides in configuration?

This is the question to be answered in this assessment.

Advantages:

1 and 45.75 million pixels have no low-pass sensor, and the resolution is superior.

2, the top tolerance performance, -5 to +2 files to restore normal exposure can still be used;

3. The comprehensive level of focusing, continuous shooting and photometry is high, which fully meets the needs of sports photography;

4. The touch flip screen, focus rocker and key backlight are added to the fuselage, which improves the operability.

Regret:

There is no obvious improvement in focusing performance under Live View live view.

Evaluation summary:

Nikon D850 is one of the best cameras I have ever used. The D850 is almost the pinnacle of current technology in terms of image quality, capture ability and handling performance. This time Nikon really gave everything to D850 without reservation.

Great progress in configuration and continuous improvement in details have given the D850 a brand-new shooting experience, and many old camera usage habits are no longer applicable on the D850. In the field of sports and news photography, if you don't have particularly high requirements for real-time transmission of photos and the reliability of the fuselage, D850 can also take on this important task.

There are classics and highlights. Design Evaluation of Nikon D850 SLR

Compared with D800 and D8 10, Nikon D850 has three most important changes:

1, with flip touch screen;

2. Cancel the built-in flash;

3. Add a multifunctional rocker at the back.

Besides, what are the subtle changes and classic designs of Nikon D850? Let's have a look.

▲ Nikon D850 front

▲ Nikon D850 side

▲ The touch flip screen added to the back of Nikon D850 is undoubtedly one of its biggest highlights. In practical use, this screen can be turned up and down by 90 degrees, which is very practical. The screen supports touch operation, so it is very convenient to select the focus in real time or quickly select the options in the menu.

▲ The built-in flash is cancelled at the top of ▲D850 fuselage. The disadvantage is that the flash can no longer be triggered by the internal flash, and the advantage is that the reliability of the fuselage is increased and the volume of the top is controlled.

▲ The bottom, made in Thailand, not made in Japan, will definitely become the knot of many people's D850.

The back button of D850 also supports backlight display, which can be turned on and off through the shoulder screen backlight. This is the first time that this function has appeared on an off-top adapter.

▲ The iconic four-leaf clover and driving turntable continue Nikon's classic design.

▲ Top hot boots

▲ In addition to the five regular buttons on the left, there is also a customizable Fn2 button on the back, which helps to improve operation efficiency.

▲ The original AE-L key in the right hand area was replaced by a multidirectional rocker. However, it should be explained here that this joystick is the function of AE-L in the past, except for selecting the focus. Keyboard man's abbreviation is sheer nonsense.

▲ Circular viewfinder, eye mask or other special viewfinder can be replaced. The magnification was increased to 0.75 times, exceeding 0.72 times of D5 in one fell swoop, ranking first in the history of Nikon SLR.

▲ The hinge structure of the flip screen is very firm, just try it.

▲ The addition of flip screen makes low-angle framing very convenient.

D850 adopts the design of SD and XQD dual-card slots. XQD takes care of professional users' demand for speed, while SD card takes care of ordinary users' demand for compatibility, which is a relatively mild solution.

▲ The cover of the left interface can be opened separately to enhance the sealing performance. From top to bottom are audio input and output, USB3.0 and video output interfaces. But there is no network cable transmission interface, which makes the positioning of D850 and D5 different.

▲ The focus mode selection key on the left is still familiar.

▲ The right hand refers to the preview key of depth of field and the Fn 1 function key, which can be customized.

▲ Flash synchronization interface and cable release interface are still common designs reserved for professional users.

▲ The body focus motor is still alive. Although there are few AF-D lenses now, Nikon has always maintained its obsession with old products and users.

▲ Bottom battery compartment.

▲ The battery of ▲D850 was upgraded from EN-EL 15 to EN-EL 15a, and the voltage capacity remained unchanged. The old machine can use new batteries, and the new machine can also use old batteries. If it weren't for a different color, I really couldn't see it clearly.

▲ When the Nikon D850 is not equipped with a handle, the continuous shooting can reach up to 7 sheets per second; With the handle and D5 battery, the continuous shooting can be upgraded to 9 PCs per second, and a set costs about 3,000 yuan, which is a necessary accessory for D850.

Generally speaking, Nikon D850 continues the design of Nikon's quasi-professional series, and the learning cost is very low for old users. The addition of flip touch screen, backlight button and focus selection rocker will undoubtedly improve the operability of this camera. In addition, this time Nikon actually used a backlight button and an optical viewfinder with a larger magnification than the flagship on the D850, which really made people sit up and take notice of this machine. We can't help thinking: If we can add a network cable interface and a memory card slot lock to the D850, can this machine really be called D5X (high pixel D5)?

The high sensitivity of the camera is directly related to the night scene and motion shooting ability of the camera. The better the high sensitivity of the camera, the higher the image quality in dark light, and the stronger the ability to capture moments.

Nikon D850 is equipped with a Quan Huafu sensor with about 45.75 million pixels. Compared with D8 10 of 36 million, the pixel of Nikon D850 has increased by nearly 100000. It is self-evident that high pixels bring high resolution, but generally speaking, the higher the camera pixels, the worse the high sense will be. So the question is, does the improvement of pixels have a negative impact on the high sensitivity of D850? Or with the progress of science and technology, the performance of high sense can also be synchronized with the number of pixels? Let's have a look.

The camera is placed on a tripod with an aperture of F8, so that the internal noise reduction optimization is all turned off and JPEG files are generated directly. Take a 100% enlarged screenshot of the position shown in the red box below each ISO file.

It can be seen that there is little difference in the image quality of Nikon D850 from ISO64 (lowest native) to ISO200, and there is almost no difference in noise control and picture details, and the advantages of high pixel and high resolution are also brought into full play; But from ISO400, noise began to appear in the bright part of the picture, and the picture quality began to decline. From ISO400 to ISO3200, the noise in the picture gradually increases, but the details are still well preserved; Until ISO6400, the details of the picture seem to have reached a watershed, and the picture has obviously lost the details since then; As for the last two levels of sensitivity-ISO12800 and ISO25600, if the former can barely be used, then the latter really can't be used. After all, the details and purity of the picture are lost too seriously. I only suggest that you take notes without requiring picture quality.

Nikon D850 High-Sense Image Quality Comments:

About the high-sensitivity performance of Nikon D850, it can't always bypass its 45.75 million pixels. D850 has 45.75 million pixels, which is close to 4D3 (12 million). You know, the increase of the number of pixels is not only as simple as the increase of the number, but also the photosensitive area of a unit pixel will decrease with the increase of pixels. This means that no matter how the process progresses, only a quarter of the light from each pixel of D850 enters D3.

Therefore, it is understandable that Nikon D850 has noise since ISO400.

Therefore, we suggest that when shooting with D850, the sensitivity should be controlled within ISO200 as far as possible, for example, in photography fields that require 100% amplification and require extremely high pictures, such as landscape photography. For other photography fields that have no extreme requirements for image quality, the sensitivity is controlled within ISO3200, and relatively good image quality can be obtained.

135 tolerance performance evaluation of Nikon D850, a new peak of SLR.

On the one hand, the tolerance performance of the camera is reflected in the tolerance rate of exposure errors: a camera with good tolerance performance can bring back the correct exposure through processing even if the photographer makes mistakes in the early stage (underexposed or overexposed photos);

On the other hand, the tolerance performance of the camera is usually positively correlated with the dynamic range of the camera. The better the tolerance, the larger the dynamic range of the camera. It is very instructive for us to judge the dynamic range performance of the camera in landscape shooting.

We still use IT 168 to test the camera's latitude.

The camera is placed on a tripod, with ISO64, aperture F8, fixed white balance and internal noise reduction optimization all turned off, and the highest specification RAW format is used for shooting. Manual exposure takes underexposed 5th gear, 4th gear, 3rd gear, 2nd gear, 1 gear, normal exposure, overexposed 1 gear, 2nd gear, 3rd gear, 4th gear and 5th gear respectively, and adjusts the exposure to normal exposure through Lightroom. The screenshot of the color sample area is as follows.

▲ Nikon D850 file was underexposed and pulled back to normal exposure.

▲ Nikon D850 file was underexposed and pulled back to normal exposure.

▲ Nikon D850 file was underexposed and pulled back to normal exposure.

▲ Nikon D850 exposure is less than 2 files, and it is pulled back to normal exposure.

▲ Nikon D850 was underexposed 1 file and resumed normal exposure.

▲ Nikon D850 normal exposure

▲ Nikon D850 overexposed 1 file and pulled back to normal exposure.

▲ Nikon D850 overexposed the second gear and pulled back to normal exposure.

▲ Nikon D850 overexposed for 3 gears and then pulled back to normal exposure.

▲ Nikon D850 overexposed the 4th gear and pulled back to normal exposure.

▲ Nikon D850 overexposed 5th gear and pulled back to normal exposure.

It can be seen that the underexposure and overexposure have no obvious influence on the color of the photo in the range of less than 5 files to overexposure 1 file of Nikon D850. From overexposure level 2, the color began to appear visible loss, but the overall picture was still within the available range; Then the third gear is overexposed, the color performance of the picture is obviously reduced, and the usability of the photo is also obviously reduced; Until the last 4 or 5 files are overexposed, the overall picture is obviously unavailable.

To sum up, from the perspective of color performance, the latitude of Nikon D850 is about -5 to +2 (if a little relaxation is required, -5 to +3 can be used). This tolerance means that as long as you take photos with automatic metering, there is almost no chance of making mistakes. In the current 135 full-frame camera, Nikon D850' s tolerance performance is probably hard to match.

However, it should be mentioned that even if D850 is so tolerant, it doesn't mean that you can do whatever you want. Let's take a look at the 100% enlarged screenshot of the photo just now.

▲ Nikon D850 file was underexposed and pulled back to normal exposure.

▲ Nikon D850 file was underexposed and pulled back to normal exposure.

▲ Nikon D850 file was underexposed and pulled back to normal exposure.

▲ Nikon D850 exposure is less than 2 files, and it is pulled back to normal exposure.

▲ Nikon D850 was underexposed 1 file and resumed normal exposure.

▲ Nikon D850 normal exposure

▲ Nikon D850 overexposed 1 file and pulled back to normal exposure.

▲ Nikon D850 overexposed the second gear and pulled back to normal exposure.

▲ Nikon D850 overexposed for 3 gears and then pulled back to normal exposure.

▲ Nikon D850 overexposed the 4th gear and pulled back to normal exposure.

▲ Nikon D850 overexposed 5th gear and pulled back to normal exposure.

It can be seen that when the underexposed fifth gear to the underexposed third gear is pulled back to normal exposure, in addition to fading, noise will still be obviously generated. Therefore, it is still necessary to look at the histogram and try to be accurate in the early stage. Old wizards often say that underexposed colors are better, which is probably not applicable in the digital age.

To sum up, the tolerance performance of Nikon D850 really refreshed my understanding of the tolerance of 135 format camera. The usable performance from -5 to +2 is infinitely close to that of a medium format camera.

Sports Photography High Availability Nikon D850 Figure Skating Actual Combat

Nikon D850 can achieve a maximum of 9 continuous shooting per second (add the handle to change the battery), which has reached the standard of the usual extreme speed camera (D3 is also 9). So many friends are not only concerned about the quality of D850, but also about whether D850 can be used in sports photography.

In order to test D850, the author chose to shoot a figure skating with a real knife and a real gun to test the performance of D850 in sports photography.

The competition is the final of 20 17-20 18 China Grand Prix in China, and the venue is the Capital Gymnasium.

First, the image quality.

As soon as I entered the stadium, I obviously felt that this shooting was not as simple as I expected. According to our experience in shooting outdoor football and basketball, as long as the shutter is controlled at11000 seconds, we can easily capture the moment of movement.

However, figure skating is obviously beyond my inherent cognition. Because the ice moves fast and rotates a lot, it takes at least 1/2000 seconds for the shutter to freeze the moment of figure skating. Coupled with the general lighting environment, the sensitivity of the camera should be at least above ISO 1600, and sometimes even ISO4000, which still has some challenges for D850.

However, it seems that the author's worry is unnecessary. Because there is no need to enlarge it to 100%, the D850 is still very available in actual shooting, and it is difficult to detect noise even when watching it on a 4K monitor.

After all, D850 pixels are too high, but a single pixel can't beat you. Four pixels are pressed into 1 (at this time, there are 1 1 10,000+pixels, which is more than 8 million pixels needed for 4K). Always no problem.

Second, focus.

Because the background is messy, the focus mode I chose when shooting is AF-C continuous focus+autofocus point. With this focusing system, even at the highest continuous shooting speed (9 frames per second), there are few out-of-focus or out-of-focus photos.

Third, photometry.

When shooting, the metering system of D850 is also very intelligent. For this large-scale white scene, the D850 doesn't look like other cameras, and it needs to be adjusted manually to increase exposure compensation to get the correct exposure. But "black is black, white is white", and strive to accurately restore every scene. Shooting is also completely like a top machine, and it can be used immediately without post-adjustment.

Summary:

The focusing system and photometry system of D850 have performed well in actual combat. With its high pixel advantage of 45.75 million, on the one hand, it can reduce the image to obtain higher picture purity, on the other hand, it can also cut the image to obtain a longer focal length. Therefore, D850 can not only be used in sports photography, but also bring a completely different experience from the traditional low-pixel top-level computer because of its high pixel characteristics.

Comments on other functions of Nikon D850, a century-old classic

1. Comparison of parameters between Nikon D850 and Nikon D8 10 and Canon 5D4.

Thanks to teacher ETPHOTOS for sorting out the form, so I won't read the parameters here.

Second, 8K time-lapse photography function

Nikon D850 supports 8K time-lapse short film function. There are two points to mention about this function: first, this function will generate video files directly in the machine, and it is not necessary to make them later; Second, use an electronic shutter when shooting, so you don't have to worry about losing the shutter.

Third, 4K video

There is only one thing to say about the 4K video function of Nikon D850: the whole format has no conversion coefficient.

At this point, it is better than the home next door 1.74 times. As for the rest, is it really important to speak?

Fourth, focus on the performance under the real scene.

Comment: There is no obvious change.

This is an old problem of Nikon. Compared with the all-pixel dual-core focusing technology that competitors have now fully popularized, Nikon SLR's focusing performance in real-time framing is indeed much worse. Unfortunately, this time on the D850, we didn't see any obvious changes.

Although this is not a serious injury to the operating experience, think that if others have this technology, they can make a Quan Huafu in minutes. Nikon has some constraints in this respect, and I am afraid it will lose its future.
