The Sony VG-B30AM Vertical Grip for Sony Alpha DSLR A200, A300 & A350 Digital Cameras provides improved flexibility and a more stable grip for users of the Sony α (Alpha) DSLR-A200, A300 & A350. It not only helps steady your hand in both vertical and horizontal positions, it also provides a stable platform for shooting portraits, still-life shots and other subjects requiring vertical format.
It also provides redundant controls for key functions and a shutter release that is located right at your fingertips when using the camera in the vertical position - eliminating the need for the contorted balancing act often required to access the camera controls when shooting vertically.
The Vertical Grip also holds two NP-FM500H InfoLITHIUM batteries (sold separately) - effectively doubling your shooting capacity to up to 1,500 shots, and the grip manages your power usage with automatic power switching to backup battery power for uninterrupted shooting.
