... I probably shouldn't have even mentioned it because I see it's started another "my gear is better/sharper/more rectilinear than yours". In reality, nobody sells photographs of lens resolution test charts, so the only people who are actually impressed by this data are other photographers, which really means this is just another penis-comparison contest.
Remember, it's not how rectilinear your gear is, it's how you use it!
(Sayeth the man whose gear ain't all that rectilinear )
