Excerpt: I purchased the BG for the extra battery life during our production day. Great idea, bad execution.<br />1: 1/4-20 screw is off centered.<br />2: We cannot center the lens into the matt box.<br />3: The BG does not attach firmly enough to the camera body.<br />4: When we spin the follow focus wheel, the camera body moves up and away from the BG. This effect is seem in every shot we used the follow focus.<br />5: Problem solved. We got rid of the BG.
Excerpt: I have used the grip only once. It really made a big difference for me. I have longer fingers and it made holding the camera really comfortable. I'm use to shooting a heavy camera. Even though the GH3 isn't that heavy to me, this grip made things balance out quite well.
Excerpt: A must-have for the GH3 owner. But dig deep into your wallet, because battery-not-included. (Okay, I admit I planned to purchase a 2nd battery, anyway.) The added bulk does not bother me whatsoever, since the weight gain is negligible. Panasonic should consider building this accessory into their other models. Would've loved this on my G2 and GF2.
