Of your choices, I ranked them by speed as GEli above mentioned. I threw in the Sigma for it's standard zoom range and the relative speed throughout the range, plus it has a decent close focusing range, not true macro but still decent with .33x magnificiation. I also considered throwing the 11-22 and the 35-100, but figured you were on a budget with the one's you listed. But if you have the money, I would look to those and still consider the 50 f2.
