I just bought my first dslr (Canon Xsi w/ kit lens) after using a kodak easyshare for years. I mainly take portraits of people, and honestly, I really get a lot of compliments on how they turn out. I'm in no way a professional, but I would like to purchase a better lens. Like I said, I mainly do portraits of people. I've actually done it for money for an engagement and a wedding so far (believe it or not) and the customers have been really happy with the results. I just want to get better at it and I think a better lens would help (along with some composition and lighting lessons). So far, all I have is the kit lens. I don't want to spend tons and tons of money either, because, like many of us, I'm liftin' the cushions to buy a cheeseburger. One more thing to mention: I really do rely on the autofocus because I have bad eyes and when I depend on my own eyes for focusing, it never turns out good. So I would like the lens to have the autofocus option available. Any suggestions would be greatly appreciated. Thanks!
