Love note to the nit pickers.

Seems to be some sensible (also some nit picky) discussion about the way I shot this test, IE: focusing on the center and examining the corners.

Yes, I am aware that I could manually focus on the corners of the image instead of focusing on the center. This would give a critical test suited to the lab, which is really nice sometimes.

But who the heck shoots that way? When I shoot an image, I am focusing on a subject which may or may not be in the center of the frame. But I still want the corners to look as good as possible, especially when I am forced to shoot wide open at f/4 (events, low light, action, etc.)

Therefore I shot examples focusing on the center, but examined the corners. All the centers at f/4 look pretty good, which we expect. But the key is how the corners will behave when the center is sharp. Bokeh be damned, I want those corners to look crisp on a real assignment, not in the lab.
