to , Madison and the original poster....that is also why i recommended the Canon 17-40L...it is a great lens, has top notch build quality, superior optics, although you lose a stop. But I don't think that matters to much on a walk-around(which the 17-40 would be on a crop), as it compares to my 28-70L, whick typically i don't use at 2.8, unless absolutely a must, or I want just a little more bokeh. You can find the 17-40 for just around$500, used on ebay or Craigslist.
