Just shot a concert few weeks ago, and if i didnt bring my 50mm I would have literally been screwed. You will need a shutter speed of around 1/20 otherwise no point shooting. The lighting was really bad on our shoot, ended up at ISO 800 f/2 and around 1/15-1/150. Lighting jumped around a hell of alot.
i think at this time of the year he's asking this question..... probably we can regard the 'concert' as 7th month 'ko tai' lor...... 七月歌台..... :bsmilie:
