This evening I was checking out the Canon EOS 40D at high ISO. The shots were taken at dusk with a 70-200mm f/2.8L IS at 200mm and f/2.8.

You can see some noise in the black, but it's really not too bad at all.

The images are not very sharp but that's because I was hand holding at pretty low shutter speeds. I'll have a talk with the raccoons tomorrow and see if I can get them to come out earlier when the light is better :)
