Hi. I have used the Sigma 30mm f/1.4, and it was a close contest between the 2 lens. The Sigma is the faster lens, and the f/1.4 is very useful. However, the Sigma was also significantly more expensive, and the Nikon won because of its better value.
understood... thx u... i may b getting 35mm and 17-50 together.... good idea?
