It's definitely a "starter" lens to learn what zoom photography is all about. It's easily light enough to carry about hand held for a day too. The macro is not true macro (only 1:2) but again, as a starter lens, it will give an introduction to that field of photography as well.
You will love this lens for those reasons if you work within those limitations.
You will also one day upgrade as well to some pristine glass, but when you do, you will know exactly what you want & how to get the best out of your new $1000+ lens because of all the training work you did on your $100 consumer Tamron :D
(bought mine in Europe, I'm sure it's cheaper to get in the US somewhere)
