I'm only taking two lenses, and I'm taking the Sigma 18-35 f/1.8 and the Nikon 85 f/1.8. I expect to use the 18-35 most of the time.
I had the Nikon 35 f/1.8, and it's a lot smaller, lighter,and cheaper than the Sigma 18-35, but the Sigma is so much more versatile, and it should be wide enough.
The Nikon 85 f/1.8 is my favorite of the Nikon primes, and will be used for photographing parades, our high school marching band, and animals. I'm pretty sure I can use my feet or crop later if I need the 50 mm distance.
