i was thinking of getting a 3rd party grip, but then read some reviews and since the d700 + a 14-24, or 24-70 lens is so heavy, and the 3rd party grips are made of a cheaper plastic, they were saying when you have it on a tripod the weight will be pulling on the connection between the grip and camera nd you can actually see it seperating, as if one day its just going to pop out sending the camera tumbling to the ground.
