CUSTOMER FEEDBACK :
Years of development have brought us a lens that has a fast aperture of 1.8 - far faster than any consumer zoom lens - and that is sharp as a filed tack. Be forewarned about the sharpness, if you are taking pictures of people, this lens is unyielding in its sharpness and may well surprise you and your subjects whose every blemish is captured. The lens has a fabulously shallow depth of field if you want to use the 1.8 aperture to blow out a background. This lens is also ridiculously inexpensive. It is not USM - so it is a little loud. It does not have a moving focus scale.
As to the build quality - yes, it is plastic. No, it's not built like the Rock of Gibraltar.
