The RevolCam is an attachment that snaps onto your phone and lets you interchange between three high-quality camera lenses, including a wide-angle, macro, and fisheye lens. It's not like having to swap the lens on a traditional camera though – all you do is spin the accessory, and you change lenses immediately. The compact revolving design gives you so many options without adding bulk to your phone. If you're the type of photographer who wants to bring their giant DSLR everywhere but can't, the RevolCam is a solid backup option. Included with the accessory is also a built-in selfie mirror and detachable light with 230 different levels of brightness.
