Thanks, that's what I was after.

Not really what I was asking.

I wanted to know how the additional 1.3 crop factor (on top if the 1.5 previously available in some FX cameras). The D500 has two crop factors that multiply out to 2.0.

Is the camera just scaling up from two different crops of the FX sensor? Or is there some other explanation?

How is the 1.3 crop of the new Nikon D500 camera accomplished? Is it done in software, or is there optics?
