The mount is plastic and it is a lightweight lens, but optically it's better than the majority of canon's other offerings in that FOV range. I did some research before picking mine up and from what I found the next step up is significantly more expensive. Also it has IS so video looks great. I shoot mostly still but it is nice to be able to record video.
It is a slow lens, but what do you need DOF on a wide angle for anyway? Short focal length + IS means low light isn't much of a problem. As a bonus, it's got Canon written on it so it's easy to resell if you change your mind or want to upgrade.
