The Sony VG-C90AM Vertical Grip is designed for the Sony a DSLR-A900 digital camera. The grip allows you to use with 2 InfoLITHIUM batteries, providing enough power for up to 1,760 shots. Camera handling is improved with a lower point of gravity with the BatteryGrip in place, especially when long focal lenses are used.
The Grip also features a vertical shutter release and controls that make shooting with the camera in a vertical position just as comfortable as shooting horizontally. Constructed of a rugged lightweight magnesium alloy, the grip also has gasket-sealed controls that resist dust and moisture.
