Prog, how can you tell this?

If you're referring to de-centering, then the easiest way to test for it is to shoot a far away detailed subject (like a cityscape) from a tall building using the wide-open aperture. If the sharpness falls off asymmetrically then the lens is de-centered. Normally the level of sharpness in the corners should be similar (for subjects at the same distance), and slightly less sharp than the center of the frame.
