I am not a Canon man but I must confirm what Danny has just said - what lenses? - unfortunately the best (prob the most expensive) you can afford. The 'L' series are Canon'^s 'pro' quality and NOT cheap!

Otherwise, there are some excellent less pricey lenses available, I use the Tamron 28-75mm f2.8. It isn't too expensive but gives excellent results - it does not, however have the IS (image stabilisation) of many Canon lenses.

As for the camera istself, Canon have just anounced a new 400D you might find attractive
