<p>Great, thank you all. This is really helpful. I didn't find the 17-55 limited on the wide side yet, so I'll start with that lens in Asia. I might pop in to a Canon shop in KL to find something wider when I have the need for a wider lens. Maybe I even rent one to try the coming weekend.<br>
For the zoom lens, I do not use the 70-200 that often and while being non-IS, it is still a big lens in the bag. I really like the alternative coined by Dieter to go with the 85/1.8 instead. So that'll make 17-55/2.8, 24/1.4 and 85/1.8. My 17-55 will be the wide lens or the one I'll put on in unknown situations while I can use the 24 en 85 for 'special' work. The 85 will work out nice for low light shots during the afternoon/night wedding, where the 70-200 won't work without flash.</p>
