So I went to a concert with the Sony RX100. It my best camera to record videos so that's why I took it in the first place. Also I didn't know where I would be located precisely and sometimes DSLR are banned in some concerts so I didn't want to lug it around for nothing. So I chose the light option.
I ended in the second row which was pretty cool for shooting. Though the show was less dark than some concerts I've been before, I didn't expect the little beast to perform so well.
So here is a little selection from that event. ISO ranges from 125 (at the wide end) to 3200 (mostly at the long end, obviously). I'm pretty happy with the results :)
