What's your budget? And you shoot with a Canon right?
You could go for the CANON - EFS 18-135 3.5-5.6 IS it has more zoom and the glass is a bit better. Or the CANON EF-S 17-55 F/2.8 IS USM low aperture and great glass. But really expensive.
Tamron and Sigma also have some great ones and a lot cheaper but I never tried any of them.
I don't really have a budget so that's okay I will look them up and see what they can do I once had a tamron and that was no succes but I heard good things about sigma so I will take a look and see if there are any good upportunities for me there.
