I tried out the Canon 24-105f4ISL last weekend. I wish I was crazy enough to afford it.

It has a nicer range than my 17-40f4L.
There's a Tamron 28-75, a couple of Canon 50s and the 70-200 f/4 L which are all cheaper and fill in where the 17-40 drops off. And the 24-105 still doesn't have the reach of the 70-200.
I'd think the 24-105 is better suited to a FF camera than a crop sensor, as 24 * 1.6 = 38.4, which isn't wide.
I want a 24-105L + 10-22... but I have a tendency to like wide apertures, so I dunno how f/4 on the 24-105 would fair for me... I should rent one for the hell of it now that I think about it.
I have the 10-22 + 24-105 combo. I also have the Tamron 28-75 F2.8. To be honest, I have been underwhelmed by the 24-105. It gets pretty soft at F4 above 70mm. I have to stop it up to 5.6. I find my Tamron to be sharper at F4. In fact the Tamron at F2.8 is as sharp as the Canon at F4. The Canon does have IS which is nice.
Here are Canon vs. Tamron shots.
If I had to do it all over again on a crop body, I would get the EFS 10-22 (great lens!), EFS 17-55 F2.8IS, EF 35 F1.4L, and EF 70-200 F4L IS. But since I plan to go FF next go-around, I am going to sell all of my lenses save the Tamron, buy the 17-40 F4L and 70-200 F4L IS. I'll either get a 35 F1.4L or 50 F1.4. Then I'll just hope Canon releases a 24-70 F2.8L IS and sell the Tamron.
