Subject: [Leica] M9 - not much more expensive than M8?

My reading suggests otherwise.
However, It's just reading.
I have no actual experience with either
my 'blad/Zeiss lenses on a current digital back
or
digital Rodenstock, Schneider or other lenses on film.

 From what I read
the digital lens corrections
have much more to do with APO quality
and focusing all the color at the same point
than dumbed down resolution.
They're also optimized for use at larger apertures
then those traditionally used in large format photography.

In the end - I think it comes down to "systems."
Lens design (on the high end) is changing for digital.
and
older lens designs "may not" perform well on digital sensors.

As we're on the transition team
we imagine we can blend the two approaches
film systems
with
digital systems.

I expect the next 3 to 5 years
will prove that the two systems
don't mix up so very well.

Yet I'd expect a high resolution APO digital lens
which performs up to spec on a high resolution digital back
will perform better on film
than a dated, but fine performing film lens,
will on a high resolution sensor.

And I'm more than willing to be "proven" wrong.
