Full Review Nikon D850 Digital Camera for Black Friday
The Nikon D850 includes a 45.7-megapixel full-frame (FX-format) CMOS sensor not previously found in any other camera. Like many other after Nikon models, it does not have an optical low pass filter. This means there is some theoretical threat of moiré consequences in fine patterns and textures, but the revival is extra-sharp nice detail rendition.
This sensor also includes gapless on-chip micro-lenses, with the latest back-illuminated design to maximize its light-gathering capabilities. In effect, the detector's layout is reversed so the wiring is behind the light frequencies as opposed to in front, and no longer obstructs any light. The result can be seen in the D850's broader ISO range -- its predecessor, the D810, had a native ISO range of 64-12,800 (expandable to ISO 32-51,200), but the D850 features ISO 64-25,600, expandable to ISO 32-102,400. Normally, greater resolution brings a decrease in maximum ISO range, but the D850 sensor provides an improvement in both respects.
Running at 7fps the D850 offers a 51-frame raw buffer. That's very good to get a camera with this resolution, if not quite up to the standard of the Nikon D5. It has both an XQD card slot and a UHS-II compatible SD card slot, so it offers potentially quite rapid data capture for sports and action photographers.
The D850 also inherits Nikon's best autofocus system -- again lifted straight from the D5. It's 153 focus points (55 of these are user-selectable), including 99 of the accurate cross-type AF sensors, and 15 that will work with lens and teleconverter mixes with an aperture of f/8. The middle point is sensitive to -4EV, along with the remainder to -3EV, allowing the camera to focus quickly in reduced light.
Autofocus modes include auto-area, 3D color tracking, single-point AF and the choice to select the amount of continuous (AF-C) focus factors from a bunch of 9, 25, 72 or 153. In Live View, there's a new brand new AF mode that's intended to facilitate precise focusing on smaller subjects in the frame, but the key point here is that the D850 nevertheless relies entirely on slower comparison detection for autofocus. The on-chip phase-detection sensor used in the Nikon Z7 was a long way away when the D850 was created.
Exposure metering is managed with Nikon's highly-capable 180,000-pixel RGB detector -- another attribute inherited from the D5. It doesn't just handle exposure, however, as it's also used for subject-recognition and face-detection, and this data is fed back into the autofocus system for precise and precise subject monitoring.
The D850's Raw documents are, predictably, huge. A compressed 14-bit Raw file takes up 43.8MB, and this rises to 51.6MB to get a lossless compressed file. An uncompressed Raw file is 92MB.
Nikon has added two reduced picture size options when shooting in Raw or JPEG. Change the picture size from large to moderate and also the D850 will record 25.6-megapixel files (6192 x 4128 pixels), with the small setting diminishing the resolution into 11.4-megapixel files (4128 x 2752 pixels). It's unlikely you'll purchase a camera with this resolution and immediately reduced it, but Nikon has pointed to the worth of smaller raw documents for stop-motion animators, for example.
Videographers have plenty to smile about also. As it was launched, the Nikon D850 was the DSLR with everything, including in-camera 4K recording at 30fps using the full width of the detector -- which means that there's no crop variable in the 4K video mode (unlike the rival Canon EOS 5D IV, by way of instance ) along with your wide-angle lenses stay wide-angle.
You can also capture 4K time-lapse movies in-camera, but maybe not 8K time-lapse movies. Creating these needs third party applications, so although Nikon touted 8K time-lapse movies as a feature once the camera was being launched, it would be accurate to say the camera features a built-in intervalometer.
Videographers are also pleased to get aids such as a peaking display for true manual focus, and zebra patterns to help prevent overexposure. Both mic and headphone sockets are built and are situated over the USB and Type-C HDMI interfaces.
The remarkable list of features using a new in-camera focus bracketing style to create lengthy depth-of-field composites (focus stacking), as well as a new Natural Light Auto White Balance alternative, which promises optimum results in outdoor lighting.
On the back, the D850 gets the biggest optical viewfinder up to now on a Nikon DSLR, with a 0.75x magnification, and below this is a high-resolution 2.36m-dot leaning LCD. It is similar to the display on the Nikon D500 and provides touch management of menu navigation, picture browsing in playback mode and AF point placement in Live View.
The camera is powered by Nikon's familiar EN-EL15 battery but what's especially notable here is it can be used to shoot 1840 shots on a single charge -- a huge jump from the 1200-shot endurance of this Nikon D810.
Nikon utilizes its now-familiar SnapBridge connectivity for wireless image transfer to mobile devices. Images can be transferred as you shoot, and selecting the all-important down-sampling 2-megapixel mode quickly speeds up transfer times and conserves valuable storage space.
