The Vivitar PG-5DMIII Deluxe Power Grip for Canon EOS 5D Mark III holds 2 LP-E6 batteries, providing twice the power. It also includes an adapter that allows you to place 6 AA batteries for extended shooting time. The Power Grip provides a vertical shutter release button and easy power on/off switch. This option makes shooting with the camera in a vertical position just as comfortable as shooting horizontally. The Power Grip attaches through the tripod mount on the bottom of the camera.

I use this product for all kinds of events: Weddings parties, Studio Portraits, etc;; This is built better than the original; construction is miticulously done with top of the line materials. On the technical sides, it performances 120% . Electronically great and satisfying and never miss a shot. There is no negatives about this Vivitar Battery Grip
Don't blow your money on the Canon brand battery grip. This one is identical. It DOES have the thumb joystick and all the functions are the SAME as the Canon. It does NOT say Vivitar ANYWHERE on it so no one will know it's not the Canon brand. Save your money, buy the Vivitar. I did and I used the money I saved toward a used Canon 40D as a back up camera to my 5D Mark III. Win/Win
I bought this grip expecting a lightweight and somewhat durable build. I was pleasantly surprised when I picked it up and it had some heft to it and felt really well constructed. I like that I can snap the Canon battery door onto it and not have to worry about losing it. The texture of the grip is actually a little bit more grippy than the Mark III's grip. I can fit my hands around the battery grip and it feel comfortable. In order to use the grip it has an ON/OFF switch. I'm not sure if it drains the battery if you leave it on but I always turn it off when I'm done. The shutter release button, I think, is actually better than the Mark III's. The Mark III's doesn't really have defined levels of between autofocusing and releasing the shutter, but the grip does. There's a small click between each function and you can feel each level when you press down. Also, the autofocus point selection toggle is easier to use than the Mark III's I think too. The only issues I have with the grip is that the shutter speed dial is clunky feeling and the AF-ON and the other buttons don't feel like the Mark III's but they work just like they're supposed to. Also, trying to move your thumb over to adjust the aperture is kind of a stretch if you're holding the grip. But I'm sure this would be a similar issue if it was the Canon brand grip. I really like this grip though and am happy that I bought it.
