I'm planning to buy a new lens due to the fact that my two current lenses don't have a fast enough aperture for low light situations. I have a D90 and an F100 which basically means that i will need an FX lens that works on both cameras. I want a 35mm lens so it will be a 50 on my d90 and a 35mm on my F100. I was wondering if f/2 is a fast enough aperture for night and low light situations. This is the lens: http://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/1923/AF-NIKKOR-35mm-f%252F2D.html
