Hooray~I just bought a battery grip for my sweetheart Canon 400D. The price is incredibly cheap for a battery grip. You guess how much I paid for a thing usually cost more than RM300? I paid RM180 + RM10 postage, total RM190.00 for a BRAND NEW battery grip.
Let's just read the review from The Digital-Picture.
The Canon Battery Grip BG-E3 allows a full-sized portrait grip (complete with shutter release and buttons similar to the built-in grip) to be added or removed as desired - giving you the best of both worlds.
The battery cover on the 350D/400D is easily removable. Two battery holder options are provided with the Canon Battery Grip BG-E3 - both slide into the end of the BG-E3. One option allows two Canon NB-2LH batteries to be utilized (allowing about twice as many shots without a battery change). The other option allows 6 AA batteries to be used.
The surface of the full-size portrait grip is rubberized for sure handling. With the Canon Battery Grip BG-E3 installed, larger lenses are much easier to control and portrait oriented shot are more comfortable to take.
The BG-E3 is a very nice accessory for the 350D/400D!I am totally agree to the last sentence! =D
