Batery Grip BG E3 for Canon 350D & 400D

The Canon BG-E3 battery grip holds two NB-2LH batteries or six AA type batteries in a tray. If two NB-2LH batteries are inserted, power is supplied simultaneously by both battery packs. If both NB-2LH packs are fully charged then the number of frames you can capture are doubled +-1200 pictures without flash or +-800 pictures if the flash is used 50% of the time. At colder temperature (32°F) that number drops to +-900 or +-700 if flash is used 50% of the time.The BG-E3 adds a portrait grip with a vertical shutter release complete with AE/FE-Lock button, AF point selector button, exposure compensation button and Main Dial. If you use big zooms or telephoto lenses then the BG-E3 should be considered as a "must have" accessory. It gives you a much more stable way to hold the camera and also acts as a counterbalance by shifting the center of gravity. Features Include:Item Used Twice. Owner upgrading to a Canon 40D.
