I already gave you some hints but bare in mind that there are a quite a few options out there and that makes it harder to give you specifics but if you want to and pick the best lens your money can buy and that suits your needs you might want to take a peek in here and make the call on your own....lots of Canon lenses reviewed and compared, there is also a section with this guy`s suggestions according to specific needs, like travel, wedding, etc.Originally Posted by OLC37
Hope this helps.
