How did Nikon d850 9fps do it?

1. About 45.75 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.

The 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 a 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 devices.

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 the sound released by shutter 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 wide-angle lens angle 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 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 to be as low as usual.

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 features-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". More accurate color reproduction can be achieved when shooting with natural light in various scenes. The size of the raw image can be selected according to the purpose of the image, and L, M* 1 or S *1-about 0.75 times the magnification of the optical viewfinder to support a wide field of vision-is about 8cm (about 3.2 inches). About 2.359 million pixels LCD touch screen with foldable TFT-the power-saving design supports shooting about 65,438+0,840 photos or recording about 70 minutes *2 animation clips (the duration of a single animation is about 23 minutes and 59 seconds)-in which the function of "focus change shooting" is convenient to obtain the materials (photos) needed for 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).
