Just dreams and premonitions. Reviews and MTV charts. Pictures of the lens
and its results.  Interviews. Common sense.
I remain the only person on any photo list who gets is opinions thrown back
at him if he doesn't have a notarized receipt of the item at hand. It makes
me feel very special. I've notice the most I get in trouble on this list is
when I say something positive about a Leica product. And that's with people
who own the older version of that product who feel they've made a life long
investment so really its about the bottom line.. Its a big problem with
Leica that they keep making better and better products. This can be quite
annoying to people who have bought early versions of transition items and
expect them to be completely  viable in decades to come.
