Daniel, I'm not intending to diss your equipment, but independant tests (by
N and C owners) suggest that the tested N and C zoom lenses don't reach
their peak performance until stopped down a couple of stops wheras the
tested Leica zoom's performance is close enough to peak at full aperture
that stopping down is only needed to control DOF.  I think you're reading
too much into this.  Please re-read my initial post.  I wrote: "unlike many
of the competitors' zoom lenses the Leica zooms are fully usable at maximum
aperture."  This means that SOME other zooms need to be stopped down for
BEST performance.  I didn't write that EVERY non-Leica zoom is crap at full
aperture.  Chill, dude.
