NEX 6 + Carl Zeiss 24mm/f1.8 = good combo?

Ive been looking at cameras lately and I have come to realize that I dont want a dslr yet, upon researching for cameras I came across the Sony NEX 6 and I saw that it was a fantastic camera. Now I found the carl zeiss lens 24mm but my question is..is it much better than the kit lens? and final question is this a great combo?
