So I'm pretty sure I'm getting the Canon Rebel XSI and have decided to forgo the kit lens for something a bit nicer. I've had a rebel xti and the canon 100mm f/2.8 usm macro and unfortunately had to return a loaned EF 70-200mm f/2.8L usm telephoto (amazing). I'm planning on picking up something like that telephoto sometime in the future (not now, too expensive) My budget for a lens currently is 300-500 (not very much I know) so I was wondering what a good/decent walk around lense would be, an all around performer (if it exists), and perhaps a decent portrait lens. perhaps I should clarify that my budget for each is 300-500 not 500 total for both lenses.
