I emailed a company in Okc and asked about a lens here is what i got back
Catrina,
Thanks for the e-mail. The least expensive lens for your Rebel would be the Tamron 80-210 for $119.99. A protective filter would be $9.49.

( here is my ? is this a "ok" lens? ( will it be much better then the one that came with the digital rebel? i think that one was a 18-55
also will i need to buy anything elese so i can use it?
thank you SO much in advance
