Proving that speed and resolution can indeed coexist, the Nikon D850 is a multimedia DSLR that brings together robust stills capabilities along with apt movie and time-lapse recording. Revolving around a newly designed 45.7MP BSI CMOS sensor and proven EXPEED 5 image processor, the D850 is clearly distinguished by its high resolution for recording detailed imagery. The back-illuminated design of the sensor is able to acquire greater detail and clarity when working in low-light conditions, and the sensor also forgoes an optical low-pass filter for improved sharpness. Working in conjunction with the sensor is the EXPEED 5 image processor, which together afford a 7 fps continuous shooting rate for up to 51 consecutive frames, an expandable sensitivity range from ISO 64 to 102400, and 4K UHD video recording using either a DX crop or the entire area of the full-frame sensor. An 8K time-lapse recording mode is also available, as well as additional specialized recording modes for digitizing film negatives and for focus stacking applications. Benefitting the imaging capabilities is an advanced Multi-CAM 20K 153-point AF system, which debuted with the flagship D5 and offers 99 cross-type sensors for refined focusing accuracy in a variety of lighting conditions. Checking off a number of boxes for multimedia image-makers, the D850 positions itself as not only a high-resolution DSLR but also as a camera for speed, movies, and low-light shooting needs.
Balancing the versatile imaging features, the D850 is also equally refined in its physical design. A large optical pentaprism offering a wide field of view and 0.75x magnification affords photographers a bright, clear, and realistic view for critical shooting needs. Conversely, a 3.2" 2.36m-dot LCD touchscreen is also available for live view shooting, playback, and menu navigation, and features a tilting design to suit working from high and low angles. A weather-sealed design is also employed, to suit working in a variety of environmental conditions, and the optional MB-D18 grip can be added to boost overall shooting times and continuous shooting rates. Additionally, built-in SnapBridge allows for wireless sharing of low-resolution imagery and remote live view use on a linked mobile device, and an optional WT-7a Wireless Transmitter can also be used for faster wireless transferring of files.
Benefitting the sensor is the apt EXPEED 5 image processor, which affords a wealth of speed throughout the camera system, including the ability to shoot continuously at 7 fps for up to 51 consecutive 14-bit lossless compressed raw files in a single burst. When working with the optional MB-D18 grip and EN-EL18a/b battery, this shooting rate can be increased to 9 fps, and up to 30 fps shooting is possible when working in a DX crop mode during Silent Live View. 153-Point Multi-CAM 20K Autofocus System Complementing the rendering capabilities and speed of the image sensor is the robust Multi-CAM 20K AF system, which features 153 total phase-detection points, including 99 cross-type sensors for improved subject recognition, and 55 of the points are selectable for greater compositional freedom. Benefitting the use of super telephoto lenses and teleconverters, 15 of the points, including nine selectable points, are compatible with an effective aperture of f/8, and all 153 points support working with effective aperture of f/5.6 or brighter.
Managing the abundance of focusing points is a dedicated AF engine, which offers quick response times to benefit tracking fast and randomly moving subjects, even at the top 7 fps shooting rate. The AF engine also contributes to enhanced focusing sensitivity, with all points capable of focusing -3 EV for working in very dark, low-contrast situations.
