That's exactly what I thought, but two prominent PDMLers actually saw the
material which made me hesitate. 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 ;-).
The inner barrels "feel" like those metal stepping rings or the filter threads on the front of the lenses. Are they steel?
PS: This is a real question btw. :-)
