Sigma Lenses
I swear I can tell just by looking at my pictures, the difference between Nikon and Sigma lenses, crazy?

The first time I began, and he felt he needed an f/2.8 lens, I bought a Sigma 28-105, maybe I'm crazy, but I swear I can see the difference, I was wondering if anyone out there has had good results w / an off brand lens.

I have both Sigma and Canon 35mm lenses for me and you bet I can say that the photos were taken with Sigma and were taken with Canon. Years ago I had a Minolta and Minolta and Vivitar lenses are used (Back to Vivitar lenses made of high quality) and the same thing – you could tell the difference. So Nikon Sigma – I'd be surprised if you did not notice the difference.
