It resolves well...

This graph shows the maximum resolution (as a percent of Nyquist) attained by our copy of the lens at various apertures. It uses MTF-10 criteria, which is a measure of the finest detail that can be resolved with at least 10% contrast. If that sounds complicated, just keep in mind this figure is well correlated to total resolution, though isn't as great a representation of perceived sharpness, which correlates more with MTF-50 measurements (more on that on the next slide).

Our results here show that center resolution peaks at 80% the linear resolution that can be theoretically attained, at F5.6 - a decent result. If this were resolved across the frame, you'd get about a 16MP image from this 24MP sensor. Of course it's not, but corners aren't too far behind, at 67% by F6.3. Not bad when you consider the higher resolving power demands placed on the lens by the smaller APS-C sensor... but what about perceived sharpness?
