Right now I am strongly considering the Tamron AF18-270MM F/3.5-6.3 Di II VC PZD. This lens seems to be just what I am looking for right now.
I really want a single lense that has a long zoom factor, solid image quality, and without going too expensive. I only have the kit lens that came with my Rebel XS at the moment, and this seems like an excellent lens to start off my collection.
What about everyone else? Which lens do you long to add to your collection?
