Cellphone cameras are designed for convenience, not artistic shooting. However, that never stopped anyone from finding ways to use fancy lenses for varying up their snaps. Photojojo's magnetic add-on lenses offer probably the most cleverly effective solution yet.
Designed to work with any cellphone camera, the lenses come with a self-adhesive magnetic ring that you wear permanently around the built-in optics. That way, you can simply snap the add-on lenses when needed and remove them quickly after use. No hassle.
They have two types of lenses available: a fisheye and a wide-angle/macro combo. The former gets you a 180-degree view and 0.28x magnification, aside from the familiar circular image. The latter provides a 0.67x angle of view and focus up to 10mm. Both are made from finely-machined high-clarity glass, with back and front lens cover for protection.
Over the years, cellphone cameras have improved enough to make them a decent, albeit less consistent, alternative to dedicated point and shoots. These two lenses extend what your stock handheld shooter can do, all in a simple yet ingenious manner.
Each fisheye and wide-angle/macro combo camera phone lens comes with two magnetic rings (so you can use it on more than one phone), along with a tiny strap for easier safekeeping. They can be bought individually ($25 for the fisheye, $20 for the wide/macro) and in a set ($40).
