I kind of owe him because I convinced him that I need a 24" imac to "edit his photos". (it's sooooo pretty)
This is why I refuse to look at a Mac.. all style and no subtance...
anyway, as a general walkaround lens with excellent sharpness, both the 17-40L and the 24-105L are superb.
Not to mention the second one has Image Stablisation, which is a huge bonus as it'll allow him to shoot in lower light.
If you want a clubbing lens, I second the 35mm f/1.4 L as someone mentioned previously.
In a club, he can bump up the ISO to 1600, and not bother with a flash.
Or if that's a little pricey, check out either the 50 1.4 or 50 1.8
