Photographing the Centerville post-game show following the Homecoming game. These images show the difference a couple of f-stops make. Being field side, I was able to switch to the Nikon 80-200mm f/2.8 from the Tamron 150-600mm - allowing me to lower the ISO from 6400 to 3200 and even increase the shutter speed from 1/400 to 1/500 sec.
