I said nothing about their lens barrels (try reading the words in front 
of you), which are aluminum alloy. I said something can be steel (as in 
stainless) and not have a magnet stick to it. A magnet is not a 
definitive test for all steels.

And nickel/cobalt alloys are magnetic. Or maybe you are saying Pentax uses
high chromium steel for their lens barrel?

The most common types of stainless steel are not magnetic. This is true
for the Pentax lens mounts.
