Kelvin: Optics for smartphones. Focus on What Matters!

This digital project blurs the lines between the convenience of mobile photography and the power of professional optics.

The Levenhuk Kelvin RIG20 is a professional smartphone photocage featuring mounts for extra gear, a Bluetooth remote shutter, and an ergonomic side handle with an integrated battery. This photocage is built for video bloggers, live streamers, mobile journalists, and anyone who takes mobile content creation seriously.

The Kelvin RIG20 lets you attach microphones, professional lights, external flashes, lens filters, wide-angle objectives, telephoto objectives, and macro objectives, as well as side and top handles. Mix and match them to build your ultimate mobile shooting setup.

To stabilize your shots when filming handheld, hold the photogadget by the side handle. Connect your smartphone to the built-in battery to extend your recording time by up to an hour. When you need both hands free, mount the photocage on a tripod and control the camera remotely with the Bluetooth shutter. You will get perfectly sharp photos and videos that are completely free of camera shake and blur.

Key features:

  • Two cold shoe mounts for professional lighting and audio gear

  • The side handle provides stable handheld shooting, and the built-in battery gives you an extra hour of recording time
  • Bluetooth remote shutter lets you shoot without touching the screen, so your videos and photos stay sharp and blur-free
  • Easy mounting on a tripod, monopod, or gimbal for rock-steady shots in any situation
  • Safe for your smartphone: EVA padding holds the phone firmly inside the cage and protects it from scratches
  • Compatible with any iPhone or Android smartphone
