Hmmmm....
First, NEVER send (at least without permission) files that big - it took
several minutes to download them, and (as you can see from the returned
files), the same info is contained in MUCH smaller image files...
More information is needed - if these were shot wide-open, that level of
illumination roll-off is normal for wide-angle, wide-range zooms (it is
often MUCH worse in cheap zooms); I would expect illumination to be nearly
even by around f8 (and filter-vignetting would not show wider than about f8
and would get worse with smaller stops [smaller area, but sharper edges]).
If you are after the best optics and performance, take the opposite
aproach use the best MF non-zoom lenses (see my SLE[MN] on my web page,
under "I babble") on a body with a sharp viewing system (NOT most AF
bodies...) - if you believe zooms are more "convenient" (I don't) and
just want a fancy P&S, I prefer the 24-120 (at least it is quite good
around f11... [not very convenient, though...;-]) - but maybe a good P&S
camera makes more sense than trying to turn a good SLR system into one...
BTW, I would also try removing the polarizer - most Nikkor wide-range
WA zoom images will barely miss the thin Nikkor regular polarizers, and
will vignette with thicker filter rims.
