Extreme resolution meets extreme speed.When Nikon introduced the D800 and D800E, it set a new benchmark for Dslr image quality and super high resolution photography that approached medium format. Now, five years later, Nikon proudly introduces the next evolution in high resolution Dslrs, a camera that allows photographers to capture fast action in 45.7 megapixels of brilliant resolution. With remarkable advancements across the board-sensor design, autofocus, dynamic range, sensitivity, Speedlight control, battery life, shutter and mirror drive mechanisms, Silent Photography in Live-View mode, focus shift capability and more-this is quite possibly the most impressive, well-rounded Dslr yet.Higher Resolution. Faster Speed. Greater Versatility.The D850 puts staggering image quality and impressive performance within reach of working photographers everywhere.45.7 Megapixel Back-side Illuminated Cmos SensorAt the heart of the D850 is a back-side illuminated (Bsi) Fx-format full-frame Cmos image sensor with 45.7 megapixels and no optical low-pass filter. A marvel of ingenuity, it achieves extraordinary image quality, enhanced light gathering efficiency, faster data readout and truer color with virtually no risk of moire.expeed 5 Image ProcessingExpeed 5 quickly processes all 45.7 megapixels of data for lower noise, wider dynamic range, subtle tonal and textural details, high-speed continuous shooting at approx. 9 fps and full-frame 4K Uhd movie recording.Dynamic Range Down to Iso 64The lower the Iso, the greater the dynamic range. Like the D810 before it, the D850 has the lowest base Iso of any DSLR or mirrorless camera-iso 64 (expandable down to Iso 32).Nikkor Lenses: The Gold StandardNikon has been setting the standard for full-frame lenses for over 80 years. Gold Ring Series Nikkor optics are among the finest lenses available, drawing peak performance from high-resolution image sensors like the one found in the D850.Precision at Every TurnFast continuous shooting, flagship autofocus and precise metering.Speed to Match Your VisionWith a continuous shooting speed of 7 fps or 9 fps using the optional Mb-D18 battery pack with En-el 18b/a Lithium-ion Battery, the D850 can capture those perfect moments in action from a bride walking down the aisle to gravity-defying sports shots at it's full 45.7 Mp resolution.153 Point Af SystemWith 153 focus points, 99 cross-type sensors and a dedicated Af processor, the D850 combines the best of flagship Af technology so that you can be assured that your high resolution images are as sharp as can be.autofocus Down to -4 EvFocus in near darkness down to -4 EV to capture moody low-light scenes. Suddenly, fast Nikkor primes and zooms can handle even lower light than before.A Multimedia PowerhouseRecord cinematic 4K Uhd movies in stunning full frame glory.Full Frame 4K UHDRecord 16:9 4K Ultra HD (3840x2160) in full frame glory using the total width of the D850's back-side illuminated Cmos sensor. Take advantage of the large sensor size for clean output at high Iso and for shooting with zero crop factor with full-frame Nikkor lenses3, including wide and ultra-wide angle lenses.4K and 8K Time-LapseCreate jaw-dropping 4K time-lapse movies right in-camera or exquisitely-detailed 8K time-lapse sequences of up to 9,999 full-size stills using D850's Interval Timer Mode.120 fps Slow-MotionTransform dramatic moments into dazzling fluid slow-motion sequences.
