The camera on the iPhone 4S is so good that many companies have come out with some relatively specialised equipment for filming and recording to attach to the iPhone, and the Dolly by iStabilizer is one of those, giving you the chance to take some great panning shots using just your iDevice (it also works with iPod touch).
The dolly, which also works if your iPhone is in a bumper, should allow you to create some pretty cool effects, including time lapse panning and nice travel movies.
While the $60 price point might but a few off, it’s definitely a nice bit of kit if you’re a creative professional, and it allow you to ditch the more expensive setup and rely on just your iPhone for creating some stunning panning.
The Dolly also works with other digital cameras as well as Blackberry and Android devices. You can get yours here.
