Since I'm stretching my budget to get the recently discounted 20D, I'm wondering if there are good alternative to the EF-S 17-85 IS USM.
I'm looking for something like the 18-70mm kit lens for the Nikon D70s. I've tried my friend's orig DigRebel with 24-85 mm USM and found it not being wide enough for my usage. So those Canons zooms that starts at 28mm won't do. I don't really need zoom much, but would prefer something that goes to 70mm rather than those that stops at 50 or 55mm.
The only thing I've found comparable is the Sigma AF 17-70mm f/2.8-4.5 DC Macro. Is this any good? Are there other lenses like this that's less than $400?
