We need to have a pair of fish eye lenses for Ricoh Theta S 360 degree camera. The diameter of the lens is 18, 4 mm, height is 4, 28...4, 3 mm mm and there is a 3, 9...4, 0 mm planar ring around the concave side of the lens. The thickness of the lens is 1, 20...1, 25 mm in the middle of the lens. Are you able to manufacture those or tell me where I could purchase them? Ricoh is not able to help. There are two lenses in the camera pointing in opposite sides providing a full 360 degree of view. Show More
