I am thinking of upgrading my camera. Will be getting the 60D but is torn between getting the 18-135 or 18-200 kit. I am not going for the 17-55 or 15-85, as I generally do street photography and have been frustrated previously due to insufficient zooms....yup I am a zoom person, that's why deciding between the 2...
Need your advise on which of the above can give me a better IQ. Also any possible problem that I may face with either.
