A firm, comfortable grip for vertical-position shooting with the Sony Alpha a77, a77 II, or a99 II. Buttons and controls are conveniently placed and easy to reach for greater comfort.

Holds two InfoLITHIUM batteries for extended shooting (sold separately). Stamina power for up to 1,060 shots. The battery grip does not have a charging function, so the batteries would have to be charged using the camera body.

The rugged, but lightweight, body design has gasket-sealed controls to resist dust and moisture. The grip has a 1/4" tripod mount on the bottom.

When using two batteries, the grip will automatically switch to the second battery if the first becomes depleted. Switching does not interrupt camera operation.

Accurate remaining power indicator shows remaining power in percentage. When using two batteries, indicators show which battery is being used and what percentage of life is left.
