However, unanodized aluminum (inner barrel does not have to be anodized, except perhaps some friction parts) could be easily mistaken as a bare steel. Alan said it was easily dented or something which definitely indicates it is aluminum. If the outer barrel is aluminum and the inner ones are of steel, the first thing came to my mind immediately was the different thermal expansion surely causing the distortion and stress particularly in hot summer, not a good recipe for the Limited lenses ;-).
