EF 24-105 f/4 L IS USM for general purpose lens

[Photog82]

I have the 24-105 on my 7D, had it on my 40d and am not sure what people are talking about with the IQ not being very well... don't believe it. It was awesome. Straight from the camera the contrast and sharpness is great! I still sharpen in a bit but it an excellent lens. I've had a couple of recent outings with the lens and what amazes me with it is that I can crop in a lot without affecting the image, unlike my 28-135. Let me know if you want any sample shots.

I should note that I have the Canon 10-22 lens as well for the times when I need for width.

I don't know that anyone is saying the IQ of the 24-105mm on APS-C is not good, it's just that there are other lenses that are slightly better. I've tested both the 24-105mm f/4L IS and the 16-35mm f/2.8L II on my 7D, against the EF-S 17-55mm f/2.8 IS, and while the first two are very good, the 17-55mm is slightly better (in addition to being a more generally useful focal length than either of the L lenses since one lacks a wide AoV and the other lacks a telephoto AoV).
