Moment Lenses For Mobile Photography ($50) may be the best smartphone accessory you ever own. Moment lenses provide portability with amazingly sharp images and are made with the highest quality materials. Currently two lenses are available; the tele and the wide. The lenses mount via a two-part system. A thin (about half the thickness of a credit card) metal plate adheres to your phone and the lenses lock onto the plate. Attaching the lens also works if you’re using a case. Check out Moment’s Kickstarter campaign going on now.
