I love taking photos at concerts and recently picked up the new Canon G1X to replace my older point and shoot. I went to the Bruce Springsteen concert at the Verizon Center in DC and got some great shots from the floor. The attached photos were converted to B&W using the RAW file and I did a little adjustment to contrast, shadows, cropping, etc…
All were shot in shutter priority mode at ISO 1600, f/5.8, 1/100 sec, 60mm. I was about 70-80 feet from the stage and at the max zoom range of the G1X. The G1X did really well and anyone who likes to shoot concerts should consider it, especially since there are a lot of restrictions on cameras at shows that usually prevent taking an SLR.
