The technical details: I used my EOS 500D camera with my EF 100-400mm f/4-5.6L zoom lens. Camera was set into Av mode with a fixed aperture value of f/8. This is to get best image quality out of the lens and to get wider range of focus. With lower aperture values the focus range will be more narrow which makes catching fast moving object within focus much more difficult. To get reasonable fast shutter speeds I set ISO to a fixed value of 400. I do not like to go much higher to prevent image noise. Shutter speed was calculated by camera automatically. For those fast moving object the resulting shutter speeds are quite low, but in the end I'm glad about that. Higher shutter speeds of 1/1000sec or higher would not create that beautiful motion blur. I did not have any tripod with me. I was sitting on a park bench resting my arm on my knee to stabilize myself and prevent too much camera shake.
