You might have a hard time buying just how impromptu and on the fly their product video is (after all it’s a product video), but Zacuto’s Zgrip iPhone Jr might be the answer that iPhone 3GS cinematographers are looking for. In short order it’s a hand grip with a mount that makes it a bit easier to shoot steady video than just holding the iPhone directly. The Jr. version will cost you $69, but if you buy it before August 15th they’ll give you $10 off. If you’re looking for a bit more professionalism and options then check out their Pro version. It’s just too bad neither of them have a self balancing arm alla steadycam.
