Ok I am a total Photo newb would like to learn but prob no time.

My girl however was right into photog at school etc and has since let it slide without a
decent camera etc.
Her 21st is coming up & I have bought her a Canon 400d with the standard 18-35mm 3.5
lens. We are planning a trip OS & am sure she will want to be snapping away at everything
from people to animals and architecture/countryside.
What is a good all round lens? Is there one? Preferably not $$$$.

It seems that a good lens to get is the 50mm f 1.8 for club shots ect $134 bucks from www.digitalcamerawarehouse.com.au

thanks heaps in advance.
