Decentered lens or human error
#1
Ok - I've never actually done this before; I was approx 6 feet from a 27 inch monitor when I took this image. This is the center. It actually looks ok to me but I'm not sure.[ATTACHMENT NOT FOUND]

#2
I remember Klaus said in his post that when doing this type of tests the lens should be slightly defocused. Am I wrong?

#3
You tend to see it better when slightly defocused.

However, this looks alright to me. Not 100% perfect but pretty good.

As mentioned the test doesn't cover the whole scope though - there may still be edge issues.
