I'm going to purchase a 50D within the next week or so. I'm also looking for a set of wide-angle lens and the Sigma 18mm - 200mm f/3.5-6.3 DC stood out for me in that it seems to be a good option for traveling (and not having to change to my zoom lenses all the time). Has anyone used this combination before? What where your results and feedback?
Thanks for the help!
