The feel of the objective vs. already great. the kit lenses.
I am not a professional of any sharpness tests or may make similar, but my pictures come out and see worlds better than those with the kit lenses.
With Aperture 2.8 also pictures come in lower light. Lightning I can increasingly be in your pocket.
All in all I am very satisfied and can only recommend the lens, it is a great complement to or replacement of the kit lenses for a fair price.
