This lens has an interesting combination of focal length and fastest. On APS-C cameras equivalent focal length is 45mm, which brings him closer to 50mm than a wide angle lens. A maximum aperture f / 1,4 allows use it in low light conditions. Some photographers use it for reportage photography in churches where shot with a flashlight is not permitted.

The review presented an early version of the lens, and it lacks a switch AF/MF from auto to manual focus. Later models already have such a switch.
A few words about the autofocus:
I have used the lens in combination with the camera Nikon D3100, so everything said below deals specifically with this camera.
In most scenes, t works well. But sometimes when the light is not enough, he candidly sums, and smears. So sometimes you need to tinker with the focus manually. Especially if you shoot at aperture f/ 1.4.
