Low light/High ISO experiment

I wanted to try out the low light/no flash capabilities of my new camera. With my old camera I could only get usable results up to 1600 ISO. The Canon 7D goes up to 6400! Using a can of my favorite beverage as my model I shot this at 6400 ISO with an 85 mm lens at 2.8 with a 1/200 shutter speed. I had more light in my kitchen than I'll have at events, but it was still a nice test. It's definitely grainy (I didn't apply any noise reduction) but shooting at 6400 you expect grain. I'm looking forward to trying it out at a concert in a couple of weeks.
