Pro:	- Small - Light - Cheap - Comes with hard lens hood
Con:	- Slow and noisy AF - Not suitable for fullframe only for asp-c
Review:	Fairly cheap and medium built lens. Since it's built for asp-c (cropfactor) camera's it's really light. It's pretty sharp stopped down. It suffers from the standard barreldistortion on de wide end and some CA. I can't tell you how it preforms against the standard EF-S 18-55 but on there are plenty reviews claiming it marginally better. The focus is slow and really noisy but you can't expect any more for it's price. I would recommend it if you don't have the standard Canon kit lens, I did and I'm not regretting it.
