Oh, I'm sorry. I misunderstood you.
We just got this camera at work last week, so I had to "test it out"! After about 200 pictures of anything from a soda can to this stream, I'm convinced I NEED ONE!
I was very surprised at the color of the sky in this picture. Even without a polarizing filter, it's very blue and vibrant.
I'll be sure to post some more pics from the D 40 today.
