I had my D850 order placed before 7:00 AM. I'm excited about the new camera, features and capabilities. Here's why.
The D800E was jaw dropping - not just good. I'm expecting a similar jump with the D850 and it's 46 MP.
Just as the D800E resolution was stunning, the AF accuracy of the D500 was stunning. I had a 45% improvement of sharp in focus images (with fast moving targets) compared to my D800E and 30% improvement vs. the D810. The D850 has the same AF system as the D500/D5 with a dedicated AF processor. I know how it works and can get a lot out of the AF system. The AF system is probably the biggest benefit of this camera and pairs very well with higher resolution.
The frame rate of the D500 makes a huge difference. While it's not a problem often, there are situations where frame rate matters. The D850 provides a nice step up with 7 fps, and I may or may not add the grip for an additional 2 fps. But the option of 30 fps and 8 MP images is quite useful if you really need a high speed camera. I've used that capability on the V1 and it can be very helpful.
The buffer on the D850 is around 1.3 GB - the same as the D500 and much larger than on the D800E or D810. That provides a 7.2 second burst - 51 images - before filling the buffer. This will mean more when I am looking at a series of short bursts than a single burst.
XQD / SD UHS-II cards
I'm very pleased with the speed of the XQD cards. This goes with the fast clearing of the buffer, but also means incredibly fast downloads. The flexibility of an SD card slot is nice because XQD cards and card readers are Nikon and Sony specific and not widely found.
Focus Stacking support
The ability to create a burst of frames for focus stacking is a very nice improvement. This was previously possible manually or using third party software and hardware (CamRanger) but the implementation sounds very nice.
Low ISO / High ISO Noise
Having base ISO 64 and Lo ISO 32 will be very useful for blurring water and other long exposure situations. At the high end, ISO performance will be as good or better than anything Nikon has released. Not a clear reason to purchase - but a nice benefit.
I don't shoot much video, but this camera seems built for exploring that capability. The time lapse and slow motion video capability looks very nice.
I'm sure there are other benefits, but it was past time for an upgrade. I'm not getting the grip for now. I don't particularly like a larger grip, and the higher frame rate does not seem to justify a $960 expense for grip, battery, and charger. I can rent a grip battery and charger if needed. I have too many grips I don't use and won't buy another.
