Hi Jugos, you can find more differences in everyday use between those two lenses than is present in this shot. That's why I've switched from the kit lens to Sigma 18-50 at the time of this test. Hovever, I have recently changed from Sigma 18-50 to Sigma 17-70 that satisfies my needs even more. Please check 17-70 vs 18-50 gallery for that matter. Regards, Miljenko

What I see from this test is that Nikkor has similar sharpness at all apertures, but has slightly worser contrast...

What is your personal impression?
