So why shouldn't someone expect a replacement if it is not as it should be.
"Don't repair my brand new lens if its not right - give a brand new one that
is right.  I just bought the thing!!" - Leica should make it right to the
end user who puts down the cash for a NEW product.  Right?

Unless Leica has hit upon the solution for teleportation, someone/something
had to physically move the lens (in its package) to get it from the Leica
factory to wherever you were when you inspected the lens, which means it was
quite possibly subject to jolts along this journey and, since AFAIK Leica
lenses are not hermetically sealed, variations in temperate and air
pressure.  These two conditions alone, along with the myriad of variables
such as exact quality of those exact packaging materials, the route taken,
the weather, the exact qualities of the lens and conditions affecting its
manufacturing, etc. ad nauseum mean that just about anything could have
given rise to the specks you notice.

My point is that there is no reason to automatically suspect lapses in Leica
QC because you find deviations from theoretical perfection in a "new" lens.
The world is a vast, dynamic place, and with limited empirical data and
theoretical understanding (a sample of two and little or no knowledge of the
exact circumstances surrounding manufacturing, QC, and transportation)
you're just not in a very good position to say much about correlation, let
alone causality, within it.
