I do have some difficulties to agree with these humorous points of
vieuw. Of course photographers by definition must be able to have a
large point of vieuw.

>From the beginning when Oskar Barnack had started playing with the
idea of taking pictures with a cine film, he, and later Leitz, its
technicians and engineers always did everything they could to improve,
but also to symplify this wonderfull camera. And certainly once
Grandfather Ernst Leitz I had decided to start its production. They
not only do everything to symplify production, but also in the vieuw
of after sales services i.e. repairs and maintenance (CLA etc). This
cuts costs during and after production, that's nothing new in the
economy. Don't forget Leicas are for a good part handmade, tuned and
checked. It went so far that Oscar Barnack asked to have his own
office next to the production hall with a large vieuw on it. He never
stopped improving and simplyfying a model even during production.
Break downs are often taken into consideration when cameras come back
to the factory.

A simple example; if you can have a look at every possible model of
the M-4 since it came to the market. You will never see 2 identical
models if you take a very close look at it. Dimensions and look don't
change much but for ex the tiny screws that appear on the front of the
camera holding it together, not only don't have the same look, but you
will also find them at differend places as production was improved.

Regarding the CCD and now CMOSIS captor, Leica tried to follow the
evolution of this technology verry closely and used it as soon as
possible. But they also have to do with it as it comes to   market
i.e. to make a good camera that suits their potential clients at a
certain moment. I too cursed and fumbled at these tiny spots and specs
I saw in the beginning with my beloved M-9. In time I took more care
and precautions when changing lenses. Those of us if not most of us
will certainly remember we often had to fight against dust, dirt,
specs and tiny spots etc when we worked in the darkroom. Enlarging
color and developping Ektachromes made things even worse. Moving a
darkroom to another place had sometimes catastrophic consequences.

There must be a way and a solvent that helps to clean the captor,
maybe the same way we clean our lenses i.e. carefully. But who knows
the formula of the contents of that magic and expensive bottle? Whe
certainly will find out sooner or later. I do have an idea. I will let
you know if I find out.

Regards & have a good W-E.
