EF 100-400 f/4.5-5.6L IS II
1/1600 sec @ f/5.6
Driving through Colorado I came across a herd of bison. I took my canon eos-r out and put my 100-400 on. This large male noticed me from across the field and started walking towards my position. After he positioned himself between myself and the herd he stopped and stared. He stared for a few minutes, but it seemed like an eternity. My camera pressed against my face, I made no sudden movements besides pressing the shutter release. He finally headed back toward his herd, and I celebrated my captures.
