Took my GH2 with Pentax 6mm lens to the voetbal/football/soccer tournament at my son's club. 10 year old boys (plus the occasional girl) playing some incredible voetbal. But with this lens it was more fun shooting the emotion around the game than shooting the action... Some of these kids are so concentrated on the game you can literally stick a camera in their face and they won't notice...
Here's my very short impression of the day.
