Experiment: zooming technique

This is an interesting technique I've always wanted to try but it was simply impossible with my previous camera.
The theory is quite simple: you just use the zoom while shooting (zoom from tele to wide (zooming out), the opposite way would lead to not so nice results). With a shuttes speed slow enough (1/50 sec in the example above) you can get a nice effect, putting a lot of emphasis and the focus on the central subject, while blurring all the surrounding objects and person. Yes, in this case the subject is not that interesting (just a man waiting for the green light in Akihabara), but I wanted to try this technique as soon as possible.
