With the E-510 and Zuiko Digital 11-22mm f2.8-3.5, I was able to create this zoom effect. It was simple really!
The surreal effect with the focus on the central photographer was simply magical! Dynamism was captured in a static scene.
This scene was shot in McDonald's near Chinatown KL, with the other Olympus gang for our 2nd walkabout. This walkabout covered parts of Chinatown and Central Market during Deepavali in 2007.
I just selected a slow shutter speed, say 1/5s, and used Shutter priority to override the shutter automation. With this effect, I managed to travel the focal length from 11mm to 14mm. The ISO was 100, with aperture at f3.2. And the IS did the rest!
Another example of zoom blur...

14mm to 25mm zoom, 1/2.5s, f8, ISO200
Another thing. Be sure to have steady hands; one to hold the body, the other to twist the zoom ring.
Somehow, it was so easy even with the little E-510 beginners D-SLR!!
