“C-Mount was originally developed for film cameras back in the 1920’s”
One of the great things about our Ribcage mod for GoPro Hero3/3+ and Hero4 is the fact that we use C-Mount as our lens mount (as well as M12 and CS-Mount). C-Mount was originally developed for film cameras back in the 1920’s so it’s almost 100 years old! It’s been used in film, television, Bolex, security, scientific machine vision cameras and more and there is a tremendous wealth of unused vintage lenses out there for the taking! One of the benefits of C-Mount is that you can connect just about anything!
For this video we used some 8mm D-Mount lenses from the 1950’s.
We used a simple step up ring to C-Mount and connected them to our camera (available in our shop). The results are quite excellent even at 4K. They have a unique look not seen in modern lenses, especially in the bokeh. Currently the Ribcage is the best option to use all of these lenses!
