Sony VG-C90AM DSLR Vertical Grip for the a900 a850 Cameras

This is a Sony VG-C90AM Veritical Camera Grip made for the Sony a900 and a850.  It takes 2 batteries giving you twice the shooting time.  Each battery is individually monitored by the camera body.  Also includes controls so you can shoot and use  your camera vertically.  This is a must have accessory for any serious a900 or a850 Photographer.  This is the Original Sony made grip. This is not an aftermarket, or third party grip.  The grip is in excellent condition.  Only reason I am selling is because I ugpraded from my a900 to an a99.  I am selling my a900, Flash, and this grip in separate auctions.  This comes with the original packaging, manuals, papers, and 2 generic batteries.
