Got it used locally, via eBay. Very sharp throughout 17-40mm F4. from 24-40mm range using Aperature priority, it utilizes faster shutter speed than the 24-105. F4 in the 24-40mm range is as sharp as my 24-105 at F5.6. However, I'm keeping the 24-105 as I'm hoping that 30D will be a 1.3x crop camera, which makes 17-40 less ideal of a walk-around lens than on a 1.6x crop.

For those complaining about price, considering IS lens generally cost $500 more than none-IS version, the price is not THAT bad.
As for the lens extension, hey, it's still shorter than 24-70 at 24mm, and lighter too.
However, even on APS-C senor at 24mm (x1.6) and F4.0, I notice some corner softness, which makes me think that it's not going to be pretty on a FF... maybe 1.3 crop would be best.
I'm glad to have upgraded from 17-85, and if I really need the F2.8, there's always the option of going through multiple copies of the Tameron 28-75 F2.8 for ~$400 until I find a good copy :-)
