Well, if this isn’t one of the weirdest but coolest camera modifications I’ve seen, I’m not sure what is. Canadian company, Back-Bone Gear has been performing camera modifications to GoPros and Sony RX0 cameras for a while now. They offer a range of modifications as well as kits you can implement yourself.
Their latest release is the elegant monster you see above, the Ribcage RXo II. It’s essentially a Sony RX0 II converted to accept Micro Four Thirds or C-Mount lenses, and boy does it look like it’d be fun to play with.
