Sony VG-C3EM vertical power girp. The VG-C3EM provides a Grip-shape, allowing you to get an enhanced hold for confident shooting in vertical position that is virtually the same as that in horizontal position. Also the body design makes it almost equally easy to control the camera in vertical and horizontal positions, thanks to keys and controls that are nearly the same as those on the back of the camera body. For example, the vertical grip provides a Multi Selector for fast selection of an AF point.
The VG-C3EM give you nearly 2x longer stamina due to the ability to loads two NP-FZ100 batteries in its housing. You can check the camera LCD monitor to see the remaining power of the battery in use as a percentage (1% minimum unit) on the power indicator. When the power of one battery runs out, the other battery automatically switches on to continue operation.
