The 19 f2.8 is in the same class as the Sigma 30 f2.8. Plastic build but also comes with a hood. When I help it in my hand the first time I wasn't really sure I wanted to shoot with it, not looking forward to sorting out the images. I was sure that the imges would be terrible, my experience with Sigma lenses in the past hasn't been very good, but I must state that they were on the Canon EF mount. The images are really bright and clear producign the same image quality as the 30 f2.8. So, this lens is also a keeper and I'm sure I'll be using this a lot in the coming months.
