Pros: Sharpness, no distortion, lightweight, fast focusing
Cons:
Build quality not top notch, focusing ring feels a bit plasticky at times, hood rattles a bit

This is one of those lenses which allow you to select aperture solely based on dof requirements. I find it to be equally sharp at all apertures. Perhaps there is some improvement at F8 compared to F2 but I think it just seems that way because of the dof increase. The sharpness remains all the way out in the full frame corners.

I wrote lightweight in the positive aspects section because it makes the lens easy to take with you. It is however, so light that I find myself wishing for it to be heavier sometimes in order to get more stability but that's being picky.

The focusing is very fast and very quiet. It was also accurate without calibration.

The focusing ring on my sample has a bit of play in it. The operation however, is nice and smooth. My other complaint would be the hood which is very loose fitting. If force is applied, it can emit a loud clicking noise. Still one cannot disregard the fact that for the money, this is a stellar lens.

This lens and my 5D mark II are best friends. Here is a picture taken with the combo:
