Photojojo, a combination photo hobbyist/retail site, is offering the iPhone Lens Dial, a case for the iPhone 4 and iPhone 4S that adds three lenses to the handset -- a wide angle (0.7x), fisheye (0.33x) and telephoto (1.5x).
The site was inspired by one of Apple's latest commercials for the iPhone 4S, in which it brags that the 8 megapixel camera, with special optics, in the handset is so good that it may be the only camera you need.
The optical-quality coated glass lenses from Photojojo are on a dial that can be rotated into place in front of the phone's built-in lens. The gadget gives the phone the flavor of an old Bolex 8mm movie camera.
According to Photojojo, the Lens Dial case, which sells for $249, with free shipping, is made of aircraft-grade aluminum and weighs 10 ounces. It also has two tripod mounts -- one for shooting horizontal pictures and one for vertical images.
Since the iPhone 4S was introduced last month, its owners have been flooding the Internet with photos. It's already the second-most popular camera phone for posting pix to Flickr, trailing the number one favorite: the iPhone 4.
