Since we're on the subject, I figured I'd give it a try. I'm not sure I performed the test exactly correctly, but this is what I got. Seems a bit dim, I know. And, even though the test may not have been performed at exactly the right dimensions, I'm not worried about mm accuracy on AF...just that it knows how to focus correctly. How does this look to you (btw, make sure to click on the image to view at full size)?

Looks like 18% gray to me so your exposure meter is working too.

FlipSide, from what I understand this kind of focus test has some inaccuracies at best. The focus area should be parallel to the camera sensor while your lined sheet of paper should be 45 degrees along side of it. Sorry if that doesn't make sense, and if that's wrong someone please correct me.
