What are the main features of Nikon D850?

1, about 45.75 million effective pixels and back-incident Nikon FX CMOS sensor D850 is equipped with back-incident Nikon FX CMOS sensor. It can achieve high sensitivity of ISO 25600 (which can be extended to Hi 2, equivalent to ISO 102400) and can shoot low-noise images.

D850 adopts ISO 64 (which can be extended to Lo 1, equivalent to ISO 32) to achieve a wide sensitivity range. In addition, the design without low-pass filter means that the D850 can use the high resolution of nikkor lens to create sharp and clear images.

2. Capture action pictures at continuous shooting speed of about 7 frames per second. The D850 is equipped with a back-incident CMOS sensor to support high-speed reading of a large amount of data. The image processor EXPEED 5 processes data at high speed and is equipped with improved shutter and reflector equipment. Under the combined action of these three characteristics, the continuous shooting speed of about 7 frames/second * 1 is achieved when the camera body is powered on.

At the same time, the battery box MB-D 18, the lithium-ion battery pack EN-EL18A/EN-EL18B and BL-5 battery cover are purchased separately, and the continuous shooting speed of about 9 frames per second * 1 can be realized. In addition, a lossless compressed RAW image *2 of about 5 1 14 bits or 170 12 bits can be shot in a single continuous shooting.

153 point autofocus system can accurately capture the subject (including moving objects), effectively expanding the application range of high pixel cameras. * 1 When it is set to continuous servo autofocus (AF), manual or shutter priority automatic exposure, the shutter speed is 1/250s or faster, and other settings are the default values. *2 when using 1 Sony QD-G64E XQD card and lithium ion battery EN-EL 15a/EN-EL 15, shoot ISO 100.

3. Eliminate shutter release sound and mechanical vibration, and shoot quietly with about 45.75 million effective pixels. The D850 is equipped with silent shooting function. In the instant view mode, the image sensor performs the operations usually completed by the front curtain and Hou Lian of the mechanical shutter, and can capture images quietly. This function can eliminate the sound released by the shutter and the image caused by mechanical vibration when shooting stars or celestial bodies in museums or weddings. Note: In M (Manual) or A (Aperture Priority Auto) exposure mode. In P (program automatic) or S (shutter priority automatic) exposure mode, you can hear the sound of aperture operation.

4. Support 4K Ultra HD (3840 × 2 160) animation recording. D850 supports 4K Ultra HD (3840 × 2 160)/30p animation recording, which can make full use of the angle of wide-angle lens and the high resolution presented by nikkor lens. In addition, a 4x or 5x slow-motion animation * can be recorded in full HD format (recorded at 100fps/ 120fps and played at 24p/25p/30p). Therefore, it is possible to dramatize an instant action in slow motion. In addition, a special animation shooting menu is added, and you can choose MOV or MP4 animation recording format, which provides a more convenient method for multimedia users to record animation. * No matter what setting, the image quality is fixed as "standard" and the image area is fixed as "DX format".

5. D850 with 8K interval shooting function has 8K interval shooting function. The interval shooting function can shoot images with a screen size of over 8K(8256 × 5504), and provides mute shooting options. When the interval shooting function starts the silent shooting and exposure smoothing options, it can not only effectively reduce the exposure variation from frame to frame, but also support the camera as low as? 3EV* low exposure photometric range.

Therefore, a photographer can shoot a series of exposure-optimized images, such as shooting from sunset to starry sky, or from starry sky to sunrise, without using manual exposure. D850 provides the function of batch processing a large number of RAW images in the camera. * use f/ 1.4 lens, ISO 100, 20°C, and use matrix photometry or central key photometry.

6. Other functions-equipped with RGB sensor with about 180000 pixels, which greatly improves the precision and accuracy of automatic control functions, such as autofocus (AF), automatic exposure (AE) and automatic white balance (AWB)- automatic optimization of calibration function-the camera can automatically fine-tune the picture according to the scene-white balance adds the option of "automatic adaptation to natural light", which can be realized when shooting with natural light in various scenes. -An optical viewfinder with a magnification of about 0.75 times supports a wide field of vision-About 8cm (about 3.2 inches), and about 2.359 million pixels are equipped with a foldable TFT LCD touch screen-The power-saving design supports taking about 65,438+0,840 photos or recording animation clips of about 70 minutes *2 (the length of a single animation is about 23 minutes and 59 seconds)-The "focus change shooting" function is convenient for obtaining the focus overlapping technology. It can enhance the depth of field-the negative digital conversion adapter is convenient to convert color or black-and-white film negatives into digital data (JPEG)*3- It supports radio-controlled wireless flash to improve the flexibility of multi-flash photography * 1 recorded in 12-bit lossless compression format. *2 When using the lithium-ion battery EN-EL 15a/EN-EL 15, it is based on the standards of Japan International Camera Imaging Equipment Industry Association (CIPA). *3 Need ES-2 film digital conversion adapter (sold separately).

Let's share an article about Nikon D850:

The back-illuminated sensor has high sensitivity.

First of all, before entering the objective test, let's briefly understand the sensor design of Nikon D850. I believe everyone should know that Nikon D850 has 45.75 million effective pixels, which is 9.4 million higher than the previous generation D8 10. In fact, for four years, the hardware upgrade of the sensor is not as fast as the computing power upgrade and software upgrade of the processor, so it is unrealistic to greatly improve the high sense. So for D850, as long as the high-sensitivity performance is not worse than D8 10, it is a good progress. Not only D850, but also other brands of cameras.

Nikon's official D850 sensor picture is a back-illuminated sensor with an effective pixel of 45.75 million.

However, it is worth noting that the sensor of D850 is not a traditional system, but a back-illuminated Quan Huafu sensor. It is not the first time that high pixel back-illuminated sensor has been applied in Quan Huafu. Sony A7RII used back-illuminated technology before, and the specific performance was quite successful, especially in enhancing the high sensitivity of high-pixel models. Back-illuminated sensors have natural structural advantages.

Nikon official explanation of back-illuminated sensor, back-illuminated sensor can obtain flexible wiring mode, thus reducing electromagnetic interference;

Moreover, according to official data and some sensor data, Nikon D850 draws lessons from D5/D500 in sensor design, and because of the characteristics of back-illuminated sensor, Nikon D850 has two sets of circuits, which can maintain the image quality similar to D8 10 in low sense, and enhance the gain effect of the sensor when shooting in high ISO, so as to obtain better high sense performance. Nikon started from D5 and paid more attention to the performance of high-sensitivity image quality. D5 In order to improve the high-sensitivity image quality, some low-sensitivity image quality is sacrificed. D850 has made greater efforts in this respect, reducing the loss of low-quality image to the lowest point, which is almost the same as D8 10.

In this article, let's take a look at the image quality comparison between D850 and D8 10.

Here, I also want to tell you a cold knowledge. Some friends may think that Nikon's sensors are all made by Sony, but they are not. Nikon has a complete sensor R&D and production system, but generally does not produce it by itself (cost consideration). Nikon's sensor suppliers actually include Toshiba, Sony, Panasonic and Israel's Tower? Jazz, wait. At present, the D850 sensor is designed by Nikon itself, but the production is from Tower? Jazz's hand, but from the perspective of grip and production line, can be counted as Panasonic's hand, and the D700 sensor is also Panasonic. So for Sony Dafa, Nikon said, well, I won't let one manufacturer dominate my destiny. (Note: Leica Q sensor is also Tower's? Jazz, but the production line is different)

It can be said that Nikon started from D5/D500, and the sensor design ideas have changed a little. From D800 to D8 10, we focus on the performance with low sensitivity, such as the ISO of D8 10. 64. All parameters and indicators are in a "off-chart" state. The research and development of the new generation camera pays more attention to the equalization of the overall image quality, which greatly improves the image quality and tolerance at high sensitivity. What is the actual performance of D850? Let's look at the objective test.
