(Untitled Page 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 32 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 Snap Bridge 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. Included with the D850 body is the Nikon AF-S NIKKOR 24-120mm f/4G ED VR lens; a versatile wide-angle to telephoto zoom that features a constant f/4 maximum aperture.
A pair of extra-low dispersion elements and three aspherical elements control chromatic aberrations throughout the zoom range while a Nano Crystal Coating helps to reduce lens flare and ghosting for increased contrast and clarity. A Silent Wave Motor produces fast quiet autofocus performance and Vibration Reduction image stabilization minimizes the appearance of camera shake to better enable working in difficult lighting conditions and with slower shutter speeds.
45.7MP FX-Format BSI CMOS Sensor and EXPEED 5 Processor A first for Nikon DSLRs a 45.7MP BSI CMOS sensor is used for high-resolution shooting impressive low-light quality and fast readout speeds to benefit continuous shooting movies and time-lapse recording. The back-illuminated design of the sensor affords noticeably cleaner high-sensitivity output for reduced noise when working at high ISO values up to a native ISO 25600 as well as vivid and smooth quality at sensitivities as low as ISO 64.
The sensor's design also omits the conventional optical low-pass filter in order to achieve the greatest sharpness and resolution from the sensor. 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 -4 EV for working in very dark low-contrast situations. Furthering the versatility of the focusing system different AF-area modes can be selected to support varying types of subject matter: Single-Point AF: The camera uses a single point to find focus.
Dynamic-Area AF: Available with 25 72 or 153-point selections this mode uses a primary single focus point to lock onto focus and then makes use of the surrounding points for maintaining focus while tracking erratically-moving subjects. Group-Area AF: This mode treats smaller groups of AF points as a single point for a wider field of recognition and is well-suited to tracking faces or other detailed subjects.
3D-Tracking: Using a subject's color information this mode utilizes all 153 points to maintain focus on a moving subject while half-pressing the shutter button. Auto-Area AF: This mode makes use of all 153 points to quickly identify the main subject and then prioritizes recognized faces as portrait subjects in any AF servo mode.
Lastly a unique auto AF fine-tune function can be employed to ensure the best possible focus for each mounted lens. Rather than relying on photographing distance charts this function lets you achieve precise focus manually in live view and then have the AF system calibrate itself to the fine-tuned focus position in order to alleviate front- and back-focusing issues.
4K UHD Video Recording and 8K Time-Lapse Utilizing the sensor and processor attributes for more than just still imagery the D850 is also a more-than-capable multimedia camera. Video recording is possible at 4K UHD (3840 x 2160) using either the full-frame area or a DX crop area in 30p 25 or 24p frame rates.
Full HD 1080p video recording is also supported at up to 120p for slow motion playback and video files can be saved to the in-camera memory cards or as an uncompressed file to an optional external recorder via HDMI out. Benefitting video recording a dedicated power aperture button (Pv) makes it possible to achieve smooth continuous exposure transitions when switching from light to dark areas and Auto ISO can also be used to maintain a consistent brightness when working in changing lighting situations.
Focus Peaking can be used to benefit manual focus control and a Zebra Stripes option is also available to help detect over-exposed areas within the frame. Audio recording can be handled using the built-in stereo microphone or an optional external mic can be added via the 3.5mm stereo jack for greater control over quality and live monitoring is possible via the headphone jack.
The D850 also blends both still and video capabilities with the ability to produce 8K time-lapses using the Interval Timer Mode or in-camera 4K time-lapse movies with the ability to record up to 9999 exposures for either method. This system also makes use of a silent interval timer which produces no shutter noise does not contribute to wear on the shutter mechanism and is energy efficient to maximize battery life.
Body Design A large 3.2" 2.359m-dot LCD screen is available for bright clear and vivid image playback and live view shooting. The screen has a tilting design to benefit working from both high and low angles and it is also a touchscreen for more intuitive operation navigation and settings control.
