If you are planning on sticking with a crop factor camera, I would also add the Tamron 17-50 2.8 to the list.
This looks good too.
Good to know, if I were to upgrade, and I won't for a few years, it would likely be to what ever replaces the 30D.30d works with ef-s lenses
DueyDooDah thanks for the link, I was unaware that of that review website.
There's so much to think about.
I'm sort of leaning to the 17-55 since it would work better in low light. Which one would be best taking shots of the family walking around the park?
just not by canon
