Sigma 150-600mm F5-6.3 DG OS HSM | Sports in the Field

In Dec I was able to get my hands on a Sigma 150-600mm F5-6.3 DG OS HSM | Sports in Nikon mount for short tour at one of the most famous bird photography spots in the US, Bosque del Apache. The first thing I noticed about this lens is the compact size, for a 600mm lens, its about the same size as one of my favorites, the Sigma 120-300mm F2.8 DG OS HSM | S lens. The lens weighs just over 6 pounds so it is a lot lighter, by about 2.5 lbs than my 500mm f/4 prime lens, or about 5 pounds less than a 600mm f/4 lens so its definitely easy to handle, even for handholding. The lens is compact and light enough to make handholding possible for most people after some time with the lens.
