The iPhone Lens Dial case comes with three different lenses: telephoto, fisheye and wide-angle. All three lenses are made of “optical-quality” glass, although the case is made out of aluminum.

The case is available for $250 and also comes with two different tripod mounts so the lenses can be used in either portrait or landscape mode.

Mobile apps like Instagram let iPhone users adjust the look of their photos after they take them through use of special filters and effects, but Photojojo’s new case allows users to take photos with legitimate differences, rather than altering them digitally after the fact. The accessory also improves long-distance shots by taking pictures with more scope.

The iPhone 4, and now the 4S with its 8-megapixel lens, have emerged as the best smartphone cameras on the market. Some analysts believe the 4S is even worthy of being considered a valid replacement for stand-alone digital cameras.
