There are 2 canon lens' that are awesome great lens for the money.
Nifty 50 50mm 1.8 for around $100
Nifty 250 55-250mm IS for around $250
You can't go wrong with these lens'. 55-250 was my first lens purchase after I bought T1i with 18-55mm and I loved it. After I bought 70-200 F4 IS, I gave it to my father and I miss it time to time b/c of it lightness and excellent image quality for the money spend. LoL now I miss my nifty 50... I gave that away to my younger cousin after she got into photography. I gotta stop giving things away. =)
