Any way to get a reasonable resolution chart to check out a lens at say 1 and 10 meters without spending a pile of money? I wouldn't mind spending $30 or so, but I'm not in need of a really hi dollar one. Vertical and horizontal lines, circles, line pairs. Mostly a basic overview of lens behavior? I think I've still got enough stuff to build one good enough by hand from the drafting days if I really need to. The resolution side would likely not get done if I need to DIY it.
