You might want to consider the Tamron 18-250 zoom as well (or the current version). I basically have 2 lenses, an 18-250 which I use all of the time, and a 100-400 IS from Canon.
Unless you're using a full frame, the 28 might be not quite wide enough, and you can always crop to get to the difference between 250 and 300 mm.
