As part of our image quality testing for the Nikon D7000, we've shot our resolution chart with the Sigma f/1.4 50mm lens mounted.

If you view our crops of the resolution chart's central section at 100% (or Actual Pixels) you will see that, for example, at ISO 100 the 24 is capable of resolving up to around 18 (line widths per picture height x100) in its highest quality JPEG files.
