[QUOTE="crycocyon, post: 144825, member: 13076"] This hasn't changed anything. The contention was that Nikon and other manufacturers produce [B][I]lenses made of plastic[/I][/B] and that still isn't the case. When one adds a UV-curable resin film of 0.05 to 0.2 mm thick (that's only 50 to 200 µm) at the thickest part to the surface of a glass element in order to add an aspherical correction to the element, that is a hybrid aspherical lens. It is an aspherical, molded coating added to as surface of a glass lens. All the lenses listed here with hybrid elements are made in that way. The elements themselves are still made of glass, not plastic. Show me a lens design with a lens made entirely of plastic because that is what was clearly meant. [/QUOTE]
