The Dot iPhone Panorama Lens
I haven’t purchased this yet, but I might. Click play on the video and then click and drag to pan.
Seems way cool, although you do notice a funky reflection from the bent protective housing the lens sets in. Also in the snowshoeing video the auto focus struggled to keep things crisp. All in all, who can complain about super-wicked interactive video!
Very cool! Purchase at Photojoj.com
