I've added the Sigma 30mm f/1.4 review to the other two "DX Normal" reviews I've done recently. Bottom line: buy the Nikkor 35mm f/1.8G DX if you're going to stay in DX for any length of time. Consider the Nikkor 35mm f/2D if you're in DX now but thinking about FX. The Sigma? Well, you'll need to read my review to understand why I didn't say buy it (for something).
