How heavy a lens will the Ribcage take?

We’ve tested lenses up to 800 grams and the Ribcage should be able to handle them providing that the weight isn’t too far from the camera and the camera is not subjected to violent motion. We recommend lenses 400g and under for the Ribcage AIR unless the lens is supported. We also recommend that large lenses be mounted using a lens clamp to take the stress off of the camera. This will also make your rig and the resulting footage more stable. We recommend using a measure of common sense when mounting big lenses – remember it is a tiny camera!

Is it compatible with Hero3+, White / Silver etc.?

Ribcage Mod Kit for Hero3/3+ is fully compatible with Hero3 Black and Hero3+ Black and Silver. We are developing the Ribcage with the Black versions primarily in mind because of their high end features.  The Hero3 White and Silver have a different image sensor that is not compatible.

Is the Ribcage Mod Kit compatible with the Hero4?

Yes. The Ribcage Mod Kit for Hero4 and the Ribcage AIR mod kits are compatible with both the Black and Silver models. The Hero4 Session is not supported.

How can I focus the lens when I’m not using the LCD BacPac?

We recommend using the LCD BacPac when possible, however external HDMI monitors can be connected, as well the GoPro smart phone app can be used. We prefer to use small field monitors with a focus peaking feature when we are shooting from a tripod. We offer some options for those here: http://www.back-bone.ca/product-category/screens-monitors/ When using the camera for UAV filming, we recommend setting the lens focus to infinity while connected to a monitor, and then attaching it to your gimbal or mount.

Do I need any special equipment for night vision?

The Ribcage mod does not have true amplified night vision like the military, however it can be configured to have a removable IR cut filter so it can be used to see in the dark with an IR light source. We recommend using a battery powered IR LED panel for most situations. These are readily available through a number of vendors online.

What is Ribcage?

The Ribcage is a modification kit for the popular GoPro Hero4 and Hero3/3+ models of action camera. It’s design to extend the capabilities of these cameras by allowing the user to connect virtually any lens. The modified cameras can also be attached to telescopes, microscopes, scientific and surgical imaging equipment.

What cameras does the Ribcage support?

The Ribcage Mod Kit for Hero3/3+ supports Hero3 Black and Hero3+ Black and Silver. Hero3 White and Silver are not compatible. The Ribcage Mod Kit for Hero4 and the Ribcage AIR Mod Kit each support Hero4 Black and Silver. Hero4 Session cameras are not supported.

What is the Ribcage AIR?

The Ribcage AIR is a super lightweight version of our popular Hero4 Mod Kit. It’s designed specifically for use with drones and GoPro sized gimbals. It fully supports 3DR Solo and a gimbal balancing kit is available as well. It features a new dedicated M12 lens mount to keep the weight as low as possible. The camera can also be configured to accept M12, CS, C-Mount and other lens types.

Will my WiFi remote still work?

Yes, the Ribcage modified camera is still a fully functional GoPro camera so all BacPacs, remotes and the mobile app are still supported.

Will using the Mod Kit void my warranty?

At this time yes. The camera must be opened to complete the modification.

What lenses does the Ribcage Support?

Ribcage modified GoPro cameras support M12 (also known as S-Mount), CS-Mount and C-Mount lenses directly. Virtually any other lens can be connected using optional C-Mount adapters.

What if I’m not comfortable performing the mod myself?

Back-bone also sells pre-modified cameras for those who want a completed solution. Many of our dealers provide installation services: https://www.back-bone.ca/find-a-dealer/

How can I connect my Ribcage to GoPro’s awesome mounts?

The easiest way to use GoPro’s mounting system with the Ribcage is to use ‘The Frame’ mount available in our shop or anywhere that sells GoPro cameras. GoPro mounts will support the camera along with small lenses up to about 100 grams. For large lenses we recommend using a tripod or other sturdy mounts with 1/4″-20 threads.

Will non-Ribcage AIR mods fit in the 3DR Solo?

Ribcage for Hero3/3+ and the original Ribcage for Hero4 will not fit into the 3DR Solo gimbal. Only the Ribcage AIR has been designed to perfectly fit their mounting bracket. We also recommend using our ‘Dead Weight’ gimbal balancing kit for Solo.

Does the Ribcage Mod just snap on over the lens?

No. The GoPro lens is not suitable to be modified in this way so the Ribcage is designed to be a complete lens replacement kit. The camera is opened and the image sensor is re-located. Detailed instructions are available on our support page on how to do that. Fully modified cameras are also available for purchase.

What’s the best lens?

The best lens is of course dependent on what you need to do with the camera.  1/2.3″, 1/2” and 2/3” M12, CS-Mount and C-Mount lenses are ideal. The original GoPro lens is roughly 3mm so most of our customers like to go with a more narrow ‘low distortion’ lens between 4mm and 8mm which will allow for wide to medium angle shots with low distortion to be shot in the GoPro’s ‘Wide’ mode. For people wanting soft focused backgrounds we recommend using lenses with manual focus and iris rings that are 12mm+ Full frame 35 mm SLR lenses will result in a magnification factor of 5.7x, so we’ve found that wider angle lenses are a better option depending on the application.
