The Canon BG-E2 Battery Grip is a cool accessory for discriminating photographers that seek extra shooting power, improved control when shooting vertically, and more balance when shooting with heavier lenses.
The BG-E2N was introduced into the market along with the EOS 40D. The E2N has the added advantage of a weatherproof seal to the battery compartment. If your battery grip has Direct fit that means that the battery packs are inserted into the battery grip without having to use a magazine tray.
