A professional lens at a consumer price

This lens is simply amazing.

- It is as sharp as any expensive Nikon or Canon lenses. So sharp that's only a hair behind the Nikkor 50mm 1.8.
- It is fast. At constant F2.8, it's the fastest wide-zoom lens you can get.
- The pictures it produces are very contrasty and saturated, much better than any kit lens, such as the reputed Nikkor 18-70mm.
- It is extremely small and light compared to other F2.8 lenses.
