Different extreme activities call for different gear, but one constant for most of us in today’s world is a cellular phone. They’re useful tools, especially smartphones; not just for alerting the authorities when you’re stuck somewhere but also for documenting your experiences with whatever video or still camera is built into the device.

The iPhone Lens Dial is meant to help you cut out the bulkier camera that you might prefer to carry around by offering a wider set of options than the stock Apple phone’s camera can. It’s a cradle that your iPhone slides into with a rotating dial on the front that allows you to switch between Wide Angle, Fisheye and Telephoto lens types. The cradle itself is made from aircraft-grade aluminum and features two tripod mounts, allowing for landscape and portrait photography.

The whole thing will set you back $250.
