This is great for Nikon. My current camera, the Sony a9, also shoots 20fps RAW. I rarely go over a second or two, that is all I have ever done, that is all I have ever needed.
In the below example, once I get focus, I rarely go over 2 seconds following a bird, sometimes 3 or 4 but that's tops. And by the way, the bird did enjoy breakfast.
Beauty Bill! That Sony sure got the job done. :) Jim
