Do it yourself kit ready to install on your hero3 & 3+ cameras. We can install this kit on your camera for $200.00 if you don't feel comfortable doing this modification.
Connect Your own lenses to GoPro Hero3 or Hero3+ Black with our new Ribcage mod kit! The Ribcage by Backbone is a mod that allows users to connect any M12, CS-Mount or C-Mount lens to their camera. By means of readily available adapter rings, any manual lens may be attached, including those from popular manufacturers such as Canon, Nikon and Pentax!
While you can connect any M12, CS or C-Mount lens, 1/2” and 2/3” lenses are best. Ribcage has a crop factor of 5.7 for 35mm SLR lenses, so wide angle lenses are generally more useful.
1/2.3”, 1/1.8” and 2/3” M12, CS-Mount and C-Mount lenses are ideal.
1/2” lenses are technically slightly too small for the sensor but in most cases give complete coverage.
1/3” or 1/4” lenses are not recommended because they are too small for the sensor & will cause soft edges in the video but the center will be sharp.
Auto iris lenses are not recommended as they require an external power supply in most cases.
Focal lengths ranging from 4mm up to 25mm will prove to be most useful. Focal lengths under 4mm will have a similar or more pronounced fish-eye effect than the stock GoPro lens.
We’ve found it best to use lenses labelled ‘HR’ or ‘Megapixel’ for HD shooting. 3MP, 5MP and 10MP lenses should produce outstanding results.
If you want to use the optional night vision feature of the Ribcage, IR corrected or D&N (day & night) lenses are recommended.
Only lenses with manual features are supported. The GoPro is not capable of controlling fully automatic lenses.
