We’ve designed our Ribcage Modified GoPro cameras to be as versatile as possible, with native support for M12, CS and C-Mount lenses as well as features like interchangeable filters, flange adjustment and more. There are some differences in the dimensions from the original camera however, so let’s take a look at how we can use the various GoPro mounting accessories.

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. The Frame mount is provided with our H5M12 and H5PRO modified Hero5 cameras. For large lenses we recommend using a tripod or other sturdy mounts with 1/4”-20 threads.


Ribcage H5M12 and H5PRO modifed Hero5 cameras are Karma ready so you can mount them on the drone or the Karma Grip handheld stabilizer when lightweight M12 lenses are used.

The best Ribcage option for underwater use is the H5M12 modified Hero5 Black. Its dimensions are identical to the original so it will easily fit in the waterproof ‘Super Suit’ with a wide variety of lenses. For the Hero3 and Hero4 we recommend using our 7.5mm Low Profile M12 lens which will allow the camera to fit in the Hero3/4 waterproof case! If you have an extended backdoor for your case the Ribcage and lens will fit inside so you can shoot underwater. The LCD Bacpac will not fit due to the 3.5mm added thickness of the Ribcage, so the empty space can be filled with foam or the protective plastic cap from your Ribcage kit.
