There are all kids of systems for clamping a lens onto a phone, but few are as versatile as the Beastgrip, a Kickstarter project about halfway to delivery stage. Not only will the gadget work with just about any smartphone, it'll also adapt lenses and other accessories you may already have for you SLR.
The rig consists of a sliding frame that will securely clamp your phone into position so its lens is lined up with the Beastgrip’s 37mm threaded lens mount. From there, it’s up to your gear bag, wallet and imagination.
Properly sized conversion lenses and filters will work well with little modification. Throw in enough step-down rings and/or depth-of-field adapters, however, and you can work with one of the prime lenses you already have for your SLR. The project page shows compelling results using fisheye, wide-angle, telephoto and macro lenses.
But Vadym Chalenko, the Chicago-based inventor of the Beastgrip, didn’t stop at adapting glass to your phone. The rig also includes five standard quarter-inch threaded mounts and a cold-shoe for securing a tripod, speed lights and any other accessory that will fit.
Naming this the 'Beastgrip' was an understatement. But the perfect name. This grip will use your smartphone, to position it into place to use the 37mm lens, mount it and walla! You've got a reimagined camera, before you.
