Live rock concerts are one of the most challenging scenarios that I’ve had to contend with as a photographer, even with a pro camera like the Canon 5D mkiii. The low-light performance of the iPhone 6 isn’t on par with pro cameras, but it is still damn good for a phone. The optical image stabilization of the 6 Plus seems to help a bit as well.
