This D500 is Nikon’s best DX sports camera because it’s the fastest DX camera ever: 10 frames per second, it can shoot through the flicker of typical sports arena, pool and gymnasium lighting, and it shoots at ridiculously high ISOs like 51, 200 and still looks great.
It has superb auto white balance, giving great colors in all sorts of crummy artificial lighting like LED, incandescent, fluorescent out in the real world.
The D500 is the first consumer Nikon that’s worthwhile considering for serious sports shooting. For sports, it’s a complete winner.
