This item is an accessory. It must be rented with a non-accessory item.
The Nikon MB-D18 Multi-Power Battery Grip allows the Nikon D850 to be powered by a single Nikon EN-EL18a/b battery. This is the same battery in the D5 which should give you more than double the capacity of the standard EN-EL15a that comes with the D850. This larger battery will increase the fps of the D850 to 9 fps max. The MB-D18 also provides a comfortable vertical grip with an additional shutter release and scroll wheel for easy access to the camera functions when shooting in the vertical orientation. It is also fairly compact, with dimensions of 5.9 x 2.9 x 1.7" (15 x 75 x 45mm).
This grip comes with the BL-5 Battery Cover that attaches to an EL-EN18a/b. A single battery is included with this grip but you can rent more here. This grip will NOT come with an EN-EL15a tray or battery.
Please note that the grip may only be rented with cameras or other gear and not as the only item in your order.
