Thats the problem, i am videoing it for my sister and her friends who will also be there. the concert ticket is sponsered by them. So i got to do the job. And i will be using a sony H7 for videoing instead which is quite good. Have been doing it in Sammi hongkong concert 2010, Sammi genting concert 2010, Sammi Singapore concert 2010 and now Sammi Taiwan concert 2010. I am not a Sammi fan but they are, i just tack along.
Everyone can try this trick, use you compact DSLR and viewfinder only for videoing and no marshal will stop you. if you use the LCD screen, in less that a min you will be asked to stop. And Of couse you will not enjoy the show.
