Sony VG-C99AM vertical grip for Sony SLT a99 Doubles nicely all controls to exactly the same positions to shoot in portrait. Adds 2 additional Sony NP-FM500H infoLithium batteries, makes possible to switch them during shooting :) Whenever it's needed. Extends usage in theory to 1500 shots without battery replacement (be conservative). Batteries are depleted sequentially. Running battery is magnified, onm the left. First a99 uses #1, then #2 bettery from the grip and only then the one in the camera body itself. So, its possible to change batteries in the grup when shooting the last battery in the body. a99 on steroids ;)
