This is a $300 "professional" video grip for the iPhone 3Gs. However, I can't imagine any "professional" choosing to shoot video with their iPhone, much less have a KIT to do it.
"Zacuto has the first serious solution for shooting video with the iPhone 3Gs."
The advantage, as far as I thought, with cellular video, was that you could whip the phone out of your pocket and capture whatever is going on, without the hassle of carrying equipment around with you. This, of course, completely negates that.
And for heaven's sake, it costs $100 more than the 8GB model! I'd love to interview anyone who actually buys this item.
