There is no free lunch when it comes to ultra zoom lenses -- lenses with very wide range of focal lengths. Yes you can get "good" shots, even shots that thrill. But when you compare with zooms of comparable quality that cover a narrower focal length range, or with high quality primes, you will see the difference, especially at the long end.

No question. I totally agree but still wanted to hear experience, as many of these lenses do better than others. My Canon 70-300 L is not nearly as "ultra zoom" as the Tamron 18-400 but still a rather long zoom, is crystal clear from on extreme to the other. We all want our cake and be able to eat it as well!
