It has been a while since we covered the OWLE, a device made to harness the video capturing abilities of the iPhone 3GS. Back then, the OWLE (Optical Widgets for Life Enhancement) was in a concept stage, but the OWLE Bubo is ready for pre-order.
The Bubo has a hotshoe mount with LED lights, with four tripod mounts. It has a standard 37mm lens that is threaded so you can put other lenses on it, besides the one that the Bubo already comes with. I believe that it also comes with a front-facing microphone.
