I got this shot earlier today near the Melton Hill Dam in Roane County, TN. She was between 2,000 to 3,000 feet away. I used my Canon 5d mkiv with the Sigma 150-600 Sports lens along with a 2X extention. I had to crop the photo about 70 -75%.
Thanks. She was so far away. I had a hard time getting her into focus. I decided to up the aperture to f/20 just to get everything in focus.
