Hi,
in addition to the information on Fred Miranda's website, you can find lens reviews at
www.slrgear.com and
www.photozone.de. These website offer very technical reviews, but the sample images offered and the general conclusions drawn could help you.
I can tell you that, as far as suprezoom lenses go, this one is well regarded. All zoom lenses are about compromises, none are pefect, and that's especialy true of superzooms. But most users seem to like the lens, and as a walkaround lens, it seems to be a good choice.
