Use this low profile M12 lens mount to fit lenses that won’t work with our standard M12 to CS-Mount adapter. This mount is included with our H8PRO modified cameras but it is compatible with all our ‘PRO’ & ‘SLIM’ modified GoPro cameras. Flip the mount over to add more thread to the front of the camera. Buy extra ones and lock in all your M12 lenses for quicker changes.
