Zacuto's Z-Grip iPhone Cinema Kit from steve weiss on Vimeo.
Ok this rig just goes a bit overboard, a rig for a DSLR is OK but a rig for iPhone is just crazy. Whats next a rig for Flip, bloggie and Kodak Playsport? These are camera's just to vlog and to make some snapshot vids not to make a professional movie. Especially with the same amount of money you could just go and buy a good DSLR instead.
