**Please note that this product is not necessarily for everybody. It requires you to take apart and re-assemble your camera which will void the manufacturer’s warranty. Back-bone has no control over the end user’s skill level and cannot be held responsible for accidental damage. We recommend that you view the  installation video on our support page before you buy to make sure this is right for you. If you don’t feel comfortable performing the installation yourself we also offer Hero4 Silver and Black cameras that have already been modified and tested. Contact us to inquire about our installation services if you already own a compatible camera. Many of our dealers also offer installation services.


Maximum Versatility

Never before has there been a more versatile camera than the Ribcage AIR Modified GoPro Hero4. Its small size, light weight and astonishing shooting options make it a pocket sized powerhouse. It features native CS & C-Mount lens support as well as M12 lens compatibility. Almost any popular lens type can be attached with optional adapters including Canon, Nikon, Pentax and more! Take advantage of what professional lenses have to offer: manual focus control, a more cinematic depth of field, macro shooting, optical zoom and iris control. You’ll receive a removable tripod mount so you can connect your camera to professional mounts and supports. Want night vision? Just take out the IR-cut filter so you can see in the dark with any IR light source! Have a difficult lens? Use the adjustable flange distance feature to get the perfect results.

Light as AIR

RC_AIR_5_webDesigned from the ground up to be as light as possible for increased compatibility with gimbals and drones, the Ribcage AIR Modified GoPro Hero4 is perfect for any aerial platform. Connect your favorite CS & C-Mount lenses for use on large gimbals or use the included M12 lens mount to use your camera with GoPro sized drones and gimbals. The Ribcage AIR features special mounting points for secure seating on 3DR’s Solo. Many distortion free wide angle lenses are available to get exactly the look you want.

All of the lens mounting rings are easily removable for filter exchange and sensor cleaning. Combine up to two custom filters in camera at the same time.  You won’t need filters for all your different lenses anymore, just  for the camera! Now you can use ND, cold mirror, NDVI and other custom wavelength filters with your M12 lenses, or lenses that have no filter threads on the front. Choose from our line of tried and tested high resolution lenses, or use your own. Browse through our library of high resolution lenses to find the right lens for your needs!

Vintage Glass

C-Mount has been around since the 1920’s where it was originally used on movie cameras. The Ribcage camera can accept all kinds of vintage lenses including those from 16mm movie cameras like Bolex, or 8mm C-Mount and D-Mount home movie camera lenses (adapter required). Film is a rare commodity these days, so why not give your lenses new life with Ribcage!

From Microscopes to Telescopes and Everything in Between

microscopeIn addition, C-Mount is commonly used in scientific and medical imaging equipment so the camera can be directly connected to many microscopes and telescopes! Insert custom filters in order to capture specific wavelengths.

Features include:

  • Out of the box compatibility with M12(S-Mount), CS-Mount , C-Mount lenses and accessories
  • New light weight design
  • Removable tripod mounting plate
  • New ‘Deep Socket’ M12 mount is compatible with even more lenses, reducing the need for heavy adapters
  • Adjustable flange distance
  • Combine up to two different filters of two different sizes in camera at the same time (15mm or 10mm diameter, 1mm thickness)
  • Fully compatible with the EXO mini Mounting Bracket
  • Fully compatible with the 3DR SOLO gimbal
  • Easily removable mounting rings allow access to the image sensor for cleaning
  • Adjustable flange distance

* M12 lenses under 10 grams recommended for Solo and other GoPro gimbals. Back-Bone’s ‘DEAD WEIGHT’ gimbal balancing kit for Solo recommended for best results and to reduce wear on the gimbal. CS and C-Mount lens types are too heavy for GoPro based gimbals. These are recommended only for larger platforms.

Modulus Sensor Housing

Designed for developers with special applications, our Modulus Sensor Housing provides protection and infinite lens mounting options for the GoPro Hero4 image sensor when removed from the camera. Use the included 12″ sensor extension ribbon to place the sensor away from the camera body. The sensor housing can be mounted on any standard 1/4″ – 20 mounting point using the included mounting bracket. Two back plates are provided for maximum flexibility – with two sensor housings you can use alternate back plates to mount them directly back-to-back for the smallest amount of parallax possible. Sensors can also be mounted back-to-back with an offset of 90°. One sensor in landscape and the other in portrait orientation. This allows high frame rate shooting in 16:9 modes without losing the ability to stitch a full 4K resolution* 360° video with only two cameras. The housing can be configured so that the ribbon connector comes out the back, top, bottom or right/left side. Bundle this housing with a Ribcage Mod Kit for maximum usability! Note: This product is designed for advanced users.


Package Contents:

  • 1 x Modulus Sensor Housing Kit
  • 1 x Ribcage AIR Mod Kit (Hero4)

*Final stitched output resolution depends on the shooting mode and lens being used.
