October 1, 2008.  I received my Tamron lens today and added a B&W UV-haze filter.  The following photos were taken with my tripod mounted Nikon D90, set for "jpeg normal" and aperture priority at F8.   After taking the 18-270 photos, the lens was swapped to the Nikon 18-200.  I didn't have sufficient time to match mm with mm, so I just eyeballed the settings and started shooting.  There was no post processing.

NOTE:  Enlarged files are over a 2.9 megabytes each.

October 1, 2008:  Photography is one of my hobbies and I expect expert comparisons from the Pros will be available soon.  Having the lens for just a few hours here are my initial findings:

1.  I believe my Tamron is at least equal to the Nikon 18-200 in picture quality.  

2.  My Tamron has the same "lens creep" as the NIkon.  The Tamron has a Lock switch at the 18mm position for walking around.

3.  My Tamron zoom mechanism has a slightly annoying resistance at the 70-100 mm spot.  If the camera is pointed down, the zoom is smooth, suggesting more of a design compromise rather than a mechanical defect.

October 2, 2008 hand held shooting, indoors, with and without flash:

1.  My subjective rating is that the images look sharp, with excellent color and contrast.

2.  The VC stabilization seems to work very well.

3.  The slightly annoying resistance at the 70-100 mm spot is smoothing out just a little bit with use, but is still noticeable.

4.  I didn't notice this while I was outdoors yesterday in good light, but my Tamron is slower to focus on some targets when compared to the Nikon.  Sometimes it seems to take almost 2 seconds to focus.

October 2, 2008 FINAL REPORT:  In my opinion, the Tamron 18-270 is a great daylight lens.  It is sharp over the whole range, color and contrast are excellent.  Unfortunately the slow focus in less than bright light is a show stopper for me.  My Nikon 18-200 had no problem quickly focusing in the same light where the Tamron was slow to very slow.

I have returned the Tamron 18-270 today, got my money back and bought a Nikon 16-85.  I put the Nikon 18-200 on my D80 and the Nikon 16-85 on my D90.  The D90 was the only camera used to compare the Nikon 18-200 and the Tamron 18-270 for these webpage photos.

 

UPDATE JANUARY 14, 2013

It's hard to believe that it's been 4 years since I commented on the Tamron and Nikon super zooms.  Lots of changes in 4 years:  D80 gone, D90 gone, 16-85 gone, 18-200 gone.  The basic reason for this update is that I purchased a Nikon 28-300, f3.5-5.6, VRII zoom, put it on my D800 and I'm very happy with it.

I have the Nikon "trinity", but most of my photography goes on webpages (www.travelwp.com) and sometimes a super zoom is needed as a "walk around lens".  The Nikon 28-300 on my D800 produces good color rendition, the focus is fast and the quality is excellent.  After many hours of use, the lens did develop lens creep, but just like the Tamron, it has a lock switch.  It's a little pricey at $940 USD but it does everything I want.  My first shoot with the 28-300 super zoom was:
