[Leica] Leica R-10 at Photokina 2008

There are really 2 issues....  a) Lens capability and b) vignetting

Vignetting is caused by something in the way of the light rays causing the
image sensor ( film or whatever) not to be "hit" by the full image circle of
the lens.  In the case of 35mm cameras ( as opposed to LF cameras) there is
a lot of baffling done on the lens to prevent stray light from bouncing
around inside the camera box.  The stray light causes lower contrast.  

I am not an R user, but if you look at your lenses, and see a 24x36 shaped
baffle on the rear end, that is what I am talking about.  No way can this be
used with a significantly larger sensor.  ( note: Hasselblad used a lot of
these on their lens line)

I think there is also another issue....   image quality.  Knowing Leica has
been very finicky with specs, to preserve the best image quality....   Would
they allow a lens of inferior quality to be used with a digital sensor, when
less than superior images would be quite obvious?  

This last argument favors selective lenses being forward compatible with a
larger sensor, and others being not recommended.  New lenses ( same mount)
with improved image circle for the new camera sensor seems the most likely
solution.

We may know at Photokina.....what year was that again?
