The Nikon MB-10 Multi-Power Vertical Grip adds dimension to the bottom of the N90s, making the grip larger without adding excessive weight. It enables the vertical holding of the N90s to be more comfortable and useful, providing a vertical shutter release button. The MB-10's quick-change battery clip easily slides in and out for fast power changes & accommodates either four AA-type batteries with the included MS-10 battery tray or two three-volt lithium cells using the optional MS-11 battery tray.
Also available is an optional Nicad Battery pack (NB-100) & Charger (NC-100).
Note: Also compatible with the original N90 model, but Vertical Shutter Release on the grip does not work with it.
