This is a 100% crop of an 3200 ISO available light (tungsten) handheld @ 1/60, f/3.5 at 60mm on a Tamron 28-300. Shot with 7D and focused on the nose piece. I am so very impressed w/high ISO on this camera. I do a lot of SE stuff and regularly shoot @ 1600, but being able to use 3200 is a boon for me.
