After numerous pre-announcements, teasers, rumors ..., Nikon finally officially announces the D850. Pretty much as I have expected all along, the D850 is roughly "an FX version of the D500," but I had anticipated the announcement around September 2016, prior Photokina 2016. Therefore, in my mind it is about a year late, but at least the specs look impressive so that hopefully it is worth the wait. Here are the basic specifications: 45.7MP BSI (Back-Side Illuminated) CMOS sensor, without low-pass filter 7 fps with the regular EN-EL15a batters, 9 fps with the D4/D5's EN-EL18 family battery (original EN-EL18, EN-EL18a, or EN-EL18b) inside the optional MB-D18 vertical grip. ISO range 64-25600 with extended range from 32 to 102400. Multi-CAM 20000 AF module, with 153 AF points, 99 of them cross type, same as the D5 and D500. Tilting 3.2-inch LCD toughscreen EN-EL15a battery Dual XQD and SD card slots, the SD slot is UHS-II compatible, same as the D500 4K UHD capable at 24/30 fps. Can capture 4K video with the entire width of the FX sensor. The D5 and D500 can capture 4K video with a center crop only, no pixel interpolation The MB-D18 power pack/vertical grip is a new design. It can hold another EN-EL15(a) battery, the D5's EN-EL18 (any type in that family) or six (6) AA batteries. It is a bit different from the power pack for the D700, D800, and D810 because those power packs use eight (8) AA batteries, which provide sufficient voltage to run the D700 (and D300) at a higher frame rate. With the D850/MB-D18 combination, you have to use a variation of the EN-EL18 battery to achieve the higher 9 fps. Personally, I don't particularly care about having 47.5MP vs. 36MP on the D800 and D810. IMO the actual difference will be small. I am even quite happy with 24MP on the D750, but having the Multi-CAM 20000 is a major plus. Similar to the D5 and D500, the ISO button is on the top right side of the camera body, behind the shutter release button. After using those bodies for over a year, I like the new location for the ISO button very much. The suggested retail price in the US is $3299.95, which is the same as the introduction prices for the D800E and D810. (The D800 was at $2999.95 in 2012.) The MB-D18 power pack has a $399.95 suggested price. New product images, copyright Nikon Inc.
