I'm planning to photograph some bands this coming weekend at a small local venue, but there usually isn't much lighting and it's not dynamic. They typically set the lights to a certain level/setting for an entire set and leave it alone for the most part.
I'm going to be shooting with a 6d, but i'm not sure which lens I should bring because I only want to have 1 on me. I have a 17-40 f4L and a 24-70 2.8L and I won't have a flash.
It's a small venue, so I shouldn't have too much of a problem getting close, so I wouldn't mind having the wider lens and I figured I can make up for the additional stop by bumping the ISO a bit. However, there might definitely be some situations where the extra bit of zoom may come in handy...
Which would you bring and why?
