Come on guys, he says she's not that into photography, already has the 18-55mm. and you're recommending the 50mm. prime and the 40mm. pancake...
A brand new EF-S 55-250mm f/4.0-5.6 IS II costs $199 at amazon.com and it will definitely broaden her options.
Considering the fact that beginners tend to be attached to teles more, she might even get deeper into photography.
I Loled at this comment. Remembering that the original kit lens was a fixed prime.
If she wants to go out and see the nightlife , a 50mm will do more good.
