[phone lens series available through photojojo]
These little guys work on any smart phone. They come as a set [or a la carte]....with a wide and macro lens, a fish eye lens, and a telephoto lens.
The product description reads:
How it works: each set comes with adhesive removable metal rings. The ring sticks to the back of your phone, and the Photojojo Lens attaches magnetically. Snap it on and off in an instant!
Although it is only late September, it is never too early to think about giving great gifts in December. Wouldn't these be awesome in a stocking?
