Mcoplus BG-D3400 Vertical Battery Grip Compatible Nikon

The Hahnel HN-D800 Infrapro Battery Grip for Nikon D800 Cameras is an easy way to double your shooting time
and get a better grip while shooting in portrait orientation.
This professional battery grip operates on 1 or 2 rechargeable EN-EL15 or HL-EL15 lithium-ion batteries or 6 rechargeable Ni-MH
or alkaline AA batteries for much longer shooting sessions, without having to stop to change or replace batteries.
The grip attaches securely to the camera body and there’s a vertical firing release with a lock, so shooting verticals is as easy as shooting horizontals.

This grip features a built-in infrared receiver that allows remote shooting within a range of up to 32-39′ (10-12 m).
The remote control transmitter provides autofocus before shutter release and continuous shutter release or bulb function for as long as the button remains pressed.
Built-in power management regulates the power output and detects use of Li-ion or AA batteries automatically. Batteries are not included.
