Default Best lens evaluation target?

For a good all around evaluation of a lens, I use my bookcase with the bindings and jackets of many hues of colors to be the ideal target. For precise tests I use the camera mounted on a tripod with both axes locked for multi-images at various f stops. This also works well for comparing flash vs. ambient illumination comparos. What other targets might work as well?
Sony A57 with 18-55 kit lens, Sony A200 and Sony H70
50mm f3.5 Minolta Maxxum macro
24mm f2.8 Minolta Maxxum
100-300mm Minolta Maxxum APO Zoom
70-300 Sony apo G SSM Zoom

This last one is tricky, in that few printers can accurately reproduce the colors in this or any color test chart, so when you take a photo of what you print, you need to compare the shot you took to the original you printed, not the original on the screen. But the process of printing the photo you took of the color test chart will be further limited by your printer's inability to accurately reproduce colors. Got that?

And on top of these, there are the charts I've made myself.
  • The lens is the thing.
  • 'Full Frame' is the new 'Medium Format'.
