Well i have managed to score photographing a couple of bands on sat night and kinda nervous .I was going to gamble with my 24-105 but with all the advise i have been given i have just got the 50mm 1.4 as i think light is going to be the issue so if there is any more tips you can give fire away.
I managed to get them to say yes to being there for sound check so I'm hoping to get some great shots then and put them on a usb for them .
any way hopefully all will be ok.
