Lens Choice: Sigma 30mm f1.4 vs Nikon 35mm f1.8?

[—Bryan—]

Wait, who are you buying this lens for? You or your wife?

Well, I'm presuming that spending $2-400 wouldn't go over well if the lens were just for my exclusive usage. In other words, I should think about what she'd be most comfortable using.

My dad owns the Nikkor and I love it. I want to buy the Sigma for two reasons: I have been super impressed with my 10-20 sigma, and you can never have enough light. The step from 1.8 to 1.4 makes a more drastic difference than you would think. Not that the Nikkor isn't a fantastic value or a brilliant lens, I think it is both.

I think if I were picking between the two, I think 30mm might be a little too wide for all-the-time usage.

Plus it should be cheaper.
