Apple has generally received positive reviews for the quality of the iPhone 4 camera, but it does suffer from one problem endemic to all phone cameras and compact cameras: you’re stuck with just one lens. CompuExpert is looking to change that, offering Digital King fish-eye and 2-in-1 wide-angle/macro lenses especially for the iPhone 4. They connect to the iPhone using special magnetic mounts—no disassembly required—and they work with or without the iPhone 4′s flash.

The lenses were designed by Japan’s Todo Seiko. The fish-eye lens enables iPhone 4 users to capture a 180° field of view, or use the distortion at the edges of the image to create those classic fish-eye effects. The 2-in-1 wide-angle/macro lens is perhaps more interesting, though: as a wide-angle lens, it features a 0.45 magnification and a 90 to 100 degree viewing angle: great for fitting a whole group or room into a shot when you can’t get very far away from your subjects. The macro function also offers 4× magnification for those intriguing close-up shots.

The Digital King lenses are available now, with the fish-eye lens going for $59.99, and the 2-in-1 wide-angle/macro lens going for $49.99. Both come with a carrying case "that wasn’t knitted by your grandma.”
