Though it’s certainly not a necessity, the Sony VG-B30AM Vertical Battery Grip is a nice addition to the Sony A300/A350 for those with larger hands. It also allows for an easier hold on the camera when shooting vertically, providing a good counter-balance for long lenses. It includes a secondary shutter release, Command dial, EV/AV adjustment button, and an AE Lock button, duplicating the controls on the camera itself. Finally, it doubles your battery life when you’re on a long shoot, because it holds two batteries, delivering up to 1,500 shots. It costs $249.99 and is available from www.sonystyle.com .
