I am becoming curious about this, as I never disassembled a lens myself. Both you and P�l (who actually saw the material) say that the inner barrel is of steel so I believe it. But if the outer casing is aluminum, there could be a problem. If you found definitively what the material of the inner barrel is, please let me know. For now, I assume it's steel (although it's heavier and harder to machine). It was actually Mr.Hirakawa, the designer of the lens, who said that the lens was made of aluminum. I did not think he was distinguishing the outer barrel from the inner one. Is the metal barrel usually of steel or light metal? Ken
