Adding lenses to your iPhone for for photo effects isn't a new idea, but building them into a case so they're always available just might be. AppBanc is hoping to raise the funds for just such a case on Kickstarter, and they say it "rivals the performance of a 200mm camera." It includes macro, wide angle, cameo, and polarized lenses you switch out with the flick of a finger, and the company's own eZoom app that offers what they call lossless digital zooming. They're working towards a US$50,000 goal, and pledges start at just $1.
