My buddy Mike's wife just got him a sig 150-500 today for his b'day. He brought it by for me to test out the sharpness and make sure everything works. Pretty impressive image quality. These were shot jpegs, (accidentally) I always shoot raw but yesterday was printing directly from cam. So here are two samples on D3. Thanks for viewing, great lens for the price. Both shots are on the 500mm end of the lens and open all the way. Kevin P.
