Just bought a D810 and the battery grip. I've been using a battery grip on my old D200 forever and I figured this would be similar. Wrong! While I love the features and wouldn't shoot without it there is a glaring difference I neglected to notice. The old grip for the D200 allowed insertion of two camera batteries and this new one only allows one. I guess I should look closer at what I purchase.
So can the camera battery still be used in the camera with an additional battery in the grip? Of course this begs the question of how does one charge the camera battery without removing the battery grip. Unless there is a way to charge the battery in camera this is a horrible feat of engineering by Nikon.
Plenty of us need the extra power for video, time lapse and astro photography. Please tell me I'm missing something.
