Here is another shot I liked from last night.
After going through every single image from last night I'd say that both cameras do an awesome job in Low-light... The Canon 40D does it faster, but not more accurately... well actually a little less accurate because many of the images were just shy of being tack sharp unlike the K10D images were I had a much higher percentage of tack sharp images. Image quality the K10D wins because it's more natural and more detail, but when you look at these small images nobody can truly tell a difference
