I started a thread a few days ago about buying a DSLR. Well I pulled the trigger on a Canon EOS Rebel SL1 DSLR Camera Kit with 18-55mm and 75-300mm Lenses, and now want to know about lenses. From what I've read, the 75-300mm isn't great, but I bought the package because it was a great deal (like $40 more than with only the 18-55). If anything I can sell it and upgrade. Here's two I've been looking at: Canon EF 50mm f/1.8 II Lens Sigma 18-200mm f/3.5-6.3 II DC OS HSM Lens for Canon Thoughts on these? Any other budget lens (college student here) suggestions? Thanks for helping!
