People always recommend others to buy a 50mm prime lense. However, the advice is only well placed if the person has a real and strong interest in pursuing photography. Most people that I know who took this advice ended up never using the 50mm because of prime lens' impracticality, and the lens ends up being a paperweight, collecting dust.
Depending on much you are willing to pay for image quality, I'd say the following are useful, practical, and safe bets:
small budget, decent image quality:
- Canon 18-135mm IS
- Canon 18-200mm IS
bigger budget, good image quality:
- Canon 15-85mm IS
Other lenses from Sigma, Tamron, etc. might be good lenses as well, and they'll be cheaper than the Canon ones, but I am not familiar with them, so I can't make any comments about them.
