A battery grip enhances the performance of Nikon's D80 and D90 cameras.
The Nikon MB-D80 battery grip is an accessory designed specifically for the Nikon D80 and D90 digital SLR cameras. It plugs into the battery compartment, taking the place of a single rechargeable battery, and extends vertically beneath the camera. This genuine accessory enhances the functions of Nikon's advanced SLRs and is particularly useful for professional photographers.
Battery Life
The primary purpose of the MB-D80 battery grip is to extend the overall battery life of the camera. Instead of using a single battery installed in the camera's battery compartment, the battery grip allows two EN-EL3e or equivalent batteries to be used. This can double camera usage time in between battery changes. With two EN-EL3e batteries fitted, the D80 takes around 5,000 shots and the D90 around 8,400 shots.
Battery Types
The Nikon D80 and D90 require the use of EN-EL3e rechargeable batteries. Using the battery grip also allows six AA batteries to be used. This can be a useful backup solution if all other batteries have been exhausted. AA batteries are not an ideal replacement for EN-EL3e batteries because they have a lower capacity. They must be fitted using the MS-D200 adapter. EN-EL3a and EN-EL3 Li-ion batteries cannot be used in the MB-D80 battery grip.
Weight and Grip
Many photographers prefer to work with a heavier camera body, particularly when using larger zoom and telephoto lenses. The battery grip adds approximately 1 lb. of weight to a D80 or D90. The battery grip also adds greater surface area to the camera body and makes it easier to hold, especially when shooting in portrait mode.
Control
The battery grip includes a button that duplicates the functionality of the AE-L/AF-L button on the main camera button. On the D80, the button can be used for auto exposure lock or auto focus lock, depending on the camera settings. The D90 allows the button to be further customized with the custom settings a6 menu. Also included are a main command dial and sub-command dial. These are primarily fitted for ease of use when using the camera in portrait mode.
Considerations
It is recommended to always use genuine Nikon products with the D80 and D90 DSLRs. They are often more expensive but tend to be of better quality and performance. Third-party accessories and batteries can under-perform, can invalidate your camera's warranty, and may even be dangerous.
