So I am looking to replace the 18-55 which came on my Rebel XT. I think this was a good learning lense but after 5300 pics I am wanting them to turn out a bit sharper. I would like a replace this lense with one which has long reach capabilities but can also function as a walk around.
I generally do shoots with my car, portraits and such at parties, but would also like to be able to shoot motorsport and possibly some wild life (though not super long distance).
I want to spend less than $500 if possible and would like to get the broadest range of zoom possible without it reducing the image quality substantially.
A couple lenses which caught my eye were the Tamron 18-250 as well as the newer 18-270 when it comes out, or possibly the Tamron 28-300. I would imagine that you guys would be able to recommend many others which I have not seen as well as possibly rule out the ones I have considered.
Thanks
