My thoughts on the new Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports lens. See sample shots of bighorn sheep taken with this lens.

For months, I’ve been thinking about getting myself a better quality wide angle lens, but I've had a hard time deciding which model to get. Weighing in the pros and cons, seems like several models end up in a tie for #1. There are many styles of photography that I like to use a wide angle for, but I'm mostly interested in Landscape. That being said, I'm also looking for something I can use for other purposes, such as astrophotography, live concerts, or environmental portraits
