Deep Socket M12 Mount Fully automatic EOS lenses defaultThis deep socket M12 mount eliminates the added weight and bulk of the M12 to CS adapter for M12 lenses that need a little more depth than the standard Ribcage mount. Perfect for drones! Like the standard mount it will take up to two filters behind the lens so you can add NDs, IR Cuts or other specialty filters. Note: Compatible with Hero4 Ribcage mod only.
