Margin of error with fast glass (pic)

For illustrational purposes only!

I always read how people feel their lenses aren't sharp when shooting wide open.
Here's a simple test taken with the D700, and 180 f/2.8 wide open.

This is a 100% crop, and resized for the web.

Look how little room for error there truly is.

Do you honestly think it's easy to get you intended target within such a small margin of error?

Just thought I'd share a thought.
