Canon 40D with a Canon EF 100mm f/2.8 maco lens, with tripod. 1/320th second at f/7.1, ISO 320.
I started out fairly far away hand holding the camera. Since it was a little chilly, he seemed content to sun himself and let me get closer and closer. I eventually grabbed the tripod and attached the camera and moved in real close. After about 10 minutes, he slowly turned around and walked away, never seeming the least bit uncomfortable with me being there.
