Get Nikon D810 at B&H Photo.
I took a quick look at Nikon Capture NX-D in my review of the Nikon D810.
The image below was shot with Nikon D810 and Sigma 50mm f/1.4 DG HSM A. It was processed with Adobe Camera Raw and Nikon Capture NX-D (both).
Shown with HD and Ultra HD images and large crops, the settings for each program, commentary included.
