Good quality product, the price is commensurate with the quality.
This piece of glass works well for me in conjunction with a Nikon D3100; nevertheless, while I'm shooting inside of a home, I've been utilizing it for over a year, and I even forget that there is no zoom very infrequently.
Pros
Aperture, build quality, light, quite crisp, and color depth are some of the factors to consider.
