I recently purchased some iPhone photo/video lenses from Photojojo, and wanted to show you what they do to iPhone video.
I bought the 3 lens bundle, which includes a wide angle/macro lens, a telephoto lens, and a fisheye lens. They actually work pretty well. Watch my video to see the three lenses in action (along with my trusty iMicrophone).
Do you use your smart phone to take videos or photos? Check the lenses out.
