35 mm 1.4 which would you get?

The answer is to ask a question. As it happens, I often have reflective surfaces and light sources within my images and the flare resistance of the Nikon 35mm 1.4G is basically spectacular. That alone makes this unit a pleasure with which to work. I also tend to shoot a lot of street and in my experience, this is a great lens for nailing focus. Your own priorities and perspectives may vary.

I have heard good things about the Sigma but remember, test scores in perfect conditions need t be interpreted relative to your  workflow and needs.
