With the addition of my D500 I wanted to pick up a vertical grip for it.
I ended up going with the Meike brand Grip. As much as I would of liked to get a Nikon one they are way to expensive for just a grip. On my old D300/D700 the Nikon Grip would increase your FPS when using either AA batteries or the D3 batterie. But since on the D500 you dont get any extra benefits I did not see the real need to spend the extra money.
