Subject: RE: [Leica] Calibration

I think Eriwn is feeling I have taken Leica to task for a  machining
error... I have not.

The problem with my USED lens being soft until I sent it to Leica for
calibration could have been caused by the previous owners' actions, I don;t
know and don't blame Leica for this problem.  I am just happy they fixed the
error, so that I have confidence in the lens again.

My story reinforces that  the used piece again needs to be checked to see
that it too does not a have a problem especially before taking that once in
a lifetime trip.  It is also good practice that even new cameras go through
a period of user testing before that special trip or assignment.... Dropping
lenses is a fact.  Incompetent independent repair men is a fact.  Infant
mortality is a fact.  User error is a fact.  100% quality is a myth.  Test
before you accept something is working to spec.  New or used.  Especially if
the pictures you take are important to you.

To infer from a few bad examples that the state of Leica quality is below
any reasonable industry norm is untenable. If Leica cannot hold a machine
tolerance of 1/100 mm in general, they should close the doors immediately!
