Hello all, I am getting into the DSLR market and am probably going to end up going with the XT. I have a basic understanding of fixed lens vs. zoom lens but thats about it. My question is if I get a XT ($400 on Amazon), is it worth it to pay an extra $60 and get the EF-S 18-55mm kit lens or go with a fixed focal lens like the 50mm f/1.8 lens that has great reviews, is only $70 but is made out of plastic. Either way the price difference is only $10 so its really not a price thing. I just want to make sure that when I purchase a camera I am happy with my first set of lens before getting a $400 lens setup. Thanks!
