Back-Bone Ribcage: Use any lense on your modded GoPro
This DIY mod used in conjunction with the Back-Bone ribcage turns a GoPro Hero into an interchangeable lens camera. The GoPro Hero has become popular as a secondary camera for many cinematographers. But they’re restricted to using a single wide-angle fixed lens that’s not useful for non-action footages. Solution? Mod the hell out of your GoPro!
For those who are comfortable with performing some tech surgery, a Canadian company called Back-Bone is offering the Ribcage, an accessory that modifies a GoPro Hero3/ Hero3+/Hero4 Black to accept lenses. The Ribcage can be purchased as a DIY kit for $200 or fully configured with a GoPro camera for $799. It’s a substantial price difference, but it’s an option for those not too keen on taking apart something. The Ribcage lets you attach any C-mount lens, which are used 16mm movie cameras and CCTV cameras (adapters are available for attaching other mount types to the C-mount). With different lenses the user can take control of zooming, focusing, depth of field, and aperture. The accessory also includes an IR filter for infrared photography. Because the GoPro camera uses a 1/2.3-inch sensor, simply attaching a lens would result in a big 35mm-equivalent crop factor. With the Ribcage’s C-mount, Back-Bone says very little cropping will occur. https://www.back-bone.ca/product-category/ribcage_cameras/
