Pros: Light
Cons:
Could be more stable (See review)

Lighweight and can carry DSLR with 300 f/4. I was initially dissapointed by the vibrations introduced by the centre column (even at its lowest elevation). The ballhead screws on the column on a flimsy plastic base which I believe is the weak point in the mechanical chain linking your camera to the ground via this tripod.

Removing this column and replacing it with a Markins TB 20 base plate considerably improves the stability and reduces vibrations. ( http://www.markins.com/ ).

Having a good head is not enough, you use a good baseplate in order to get good results with a long lens.

I have had very good results with the Markins TB-20 baseplate and a Manfrotto BallHead ( 486 Compact) supporting a 300mm f/4. Stability and smoothness are improved a notch with a Markins Ballhead. ( and carrying capacity is greatly improved I guess but I didn't have a heavy lens/camera to test it).

Pros: Very Sharp at wide angle and good colours
Cons:
A bit less contrasy at the long end of its range.

I found this zoom Sharp and contrasty in general. The sharpness drops a bit at the long end of the range, but remains very good.
I found it to be clearly sharper than the 28/2.8 prime at f/4, particularly on the edges (tested with 1.6x sensor of the Canon EOS350D).
I also compared this lens with the very good value 50/1.8 II ( at 40mm and f/4.... ok its a big dodgy given the difference in focal length). The 50 mil was very much sharper in the centre and edges of the picture at f/4

Compared to the EFS 10-22, this lens has a comparable sharpness, it also has a small amount of CA on the edges (almost undetectable on the 10-22), and is 120grams heavier. Finally, this lense appears to include a slightly wider tonal range than the 10-22 (particularly on the warm side of the spectrum). This in my view makes the pictures a little nicer to look at, but the difference is a subtle one and may depend on the lighting conditions.

It also comes with a hood and leather bag (unlike the 10-22).

I intend to use it as my main lens, and maybe to combine it with an EFS 60/2.8 macro or 50/1.8II when travelling (where weight is an issue and you cannot bring 5 lenses with you)

Overall this looks like a very good lens.
