Do you mean wide open at infinity? How to test it?

I test all my lenses wide open at infinity ....... you can't be out of square with infinity !..... and wide open will reveal how well a lens is centered, ie; softness left and right ......

Actually, first shot tilting the camera so the horizon goes from top left to bottom right of the image and then second shot tilting the camera the other way, horizon from bottom left to top right will give you infinity detail into all four corners from the two images ...... you have all four corners for comparison ..... they should all look, equally sharp!!
