Hi Christopher,

> With the new Canon 1Ds and the excellent reviews, Nikon has to be hurting.

I believe Nikon is avoiding a fundamental problem, and that is their lense
mount.  It is possible that it is too narrow to provide adequate coverage,
without vignetting on the digital sensor, on a full frame sensor.  This is
why Contax redesigned their lense mount, and made it wider.  Unlike film,
digital sensors are recessed into wells, and therefore there is a maximum
angle that light can enter the well before causing vignetting due to the
well depth.  Film does not have this issue.

I have heard that the Canon full frame cameras have some vignetting with
their wide angle lenses, which was to be expected.

Austin
