Apple will see your Louis Vuitton and raise you an Armani. :)

You make a good point, Scott.

Admittedly, I would have had more latitude for color corrections and grading if I had true 10-bit footage. But, for my project -- an instructional video -- the ProRes footage I captured worked well.

I'd definitely like to use a higher-end camera like the Red or Arri on my next project, though.

However, if Nikon does some truly innovative things with the D850, I would consider it, too.

Here are a few high-speed external storage options:

I have high hopes for the Nikon D850.

I used the D800 to shoot a feature-length instructional video, and I was extremely happy with the results. With the camera's clean-HDMI out, I patched it into an Atomos Ninja 2 and recorded 10-bit ProRes 4:22 HQ to SSDs.

The ability to shoot 10-bit full-HD video internally would be great for the D850. Nikon would probably have to make it 4K-capable to compete in the current marketplace, though.

Even 2K would be great for the small form factor of a Nikon, which does offer some of the best lenses available.

I used the Nikon D800 in conjunction with the Atomos Ninja 2 to shoot a feature-length instructional art video, and it worked out very well.

Of course, to get the best results, I had to shoot at the D800's lowest native ISO -- ISO 100 -- so I had to thoroughly light my location. But that wasn't problematic.

Overall, I was extremely happy with the quality of the footage. I captured to ProRes 4:2:2 HQ and was able to easily import it into Adobe Premiere Pro CC for editing, color correction, and sound mixing.

Here's a trailer that I cut with the footage from the D800: https://www.youtube.com/watch?v=6tf9ZoPTUBs

I used the Nikon D800 in conjunction with the Atomos Ninja 2, and I thought it worked very well. I shot at the lowest native ISO, ISO 100, and the footage was noise-free.

I also captured the footage as ProRes 422 HQ, which was easy to import and edit in Adobe Premiere Pro.
