The official announcement is on August 24, 2017. You can see the leaked Nikon D850 press release first:
August 24, 2017 – Nikon is pleased to present the new Nikon D850 digital SLR, perfect combination of resolution, speed and light sensitivity. From studio photography to sports, to reportage in the most remote places on the planet, the new full-frame DSLR in Nikon FX format not only delivers high performance, but brings photo excellence to a whole new level.
Whether it’s naturalistic, sporting, commercial, wedding, fashion photography, whether it’s shooting movies, the D850 offers photographers who work in highly competitive fields the creative flexibility needed to excel. The fast, 45.7-megapixel FX high-resolution FX sensor is built with the “gapless on-chip” microlent technology that, together with the benefits of CMOS backlight, delivers exceptional detail sharpness along with an incredible dynamic range. The shooting speed of 7 fps can go up to 9 fps by adopting the optional MB-D18 multi power battery pack. Video-makers can then record full-size movies in 4K without clipping factor crops: this increases the chances when looking for extended field corners to resume with NIKKOR prime lens lenses. Additionally, you can record timelapse of 4K accelerated movies directly on “camera”.
The other new features that allow maximum flexibility include capturing RAW format in three different sizes: large, medium or small; The silent Photography mode, which makes it possible to shoot ultra-sharp, high-resolution images without the sound / mechanical shutter noise; The AF Pinpoint mode, available in Live View, allows you to make the auto focus more accurate and selective as required, for example, in the case of macro photography.
In addition, the Nikon D850 is the first digital reflex of all time to offer “on-camera” focus-stacking mode, which allows you to shoot a series of shots sequentially of the same shot but with the focus plane Motorized in displacement. This mode is particularly useful in macro photography, when the close distance of the subject narrows the depth of field to a few millimeters but also for artistic representations of naturalistic scenarios to enhance the extreme depth of field.
Nikon says: “The D850 offers such incredible versatility to give you the impression of working with three cameras in one. Megapixels, file size, speed, ISO … in every field, you can be assured that the Nikon D850 excels! It’s a really smart investment for photographers who want to enhance their skills and express themselves without compromise. ”
