Why the sigma and not the nikon? Well first off it was $500 less. Second: I could find it. And the quality is reportedly close to that of the Nikon. By the way it feels it id agree. As for the picture quality I dont know but ive heard its close. Also this one has a cool feature where i can manually focus while still in AF mode.
