Got my 40D zoom setup including Sigma 17-70 and Canon 70-200 F4L. It's spending-hard-earned-cash time so I've just bought a Canon 10-22 and am awaiting delivery. I am also contemplating trading in the Sigma for either a Canon 17-55 2.8 IS or a Canon 24-105L IS. (Or I could keep the Sigma and go for something else). I'm leaning towards the 24-105 as I do a lot of portraits and with the IS I reckon f4 is good enough. So I'm interested in opinions on both when coupled to the 40D. Thanks in advance
