I was at Seaworld and had my Voigtlander 40mm manual focus lens on my Nikon F80. I keep my lens focused to infinity; Zone Focus, BABY! I happen to glance up and I saw a dolphin in the air. I quickly raised my camera. As I was raising my camera I focused closer, maybe to 10 feet and took the shot. It was quick and I wasn't even really sure what I got. It was all muscle memory. I asked myself; was the dolphin still in the air?
It's not super sharp but I got the shot! Another example that Zone Focusing works.
