A downtown Salt Lake City pawnshop at night. This was shot handheld at 1/20th second, thanks to the 24-105 lens's image stabilization. It has been adjusted for contrast and density in Lightroom and Photoshop and I made a pretty big perspective correction in Photoshop.

I am really impressed with the high ISO performance of the 5D Mark II. Combine totally usable ISO 1600 and 3200 with the 24-105 f/4L IS lens and you've got a great walkaround urban camera.
