This lens is able to focus very close thus you can use the imatest chart
for resolution testing but I believe that close focus is not its strong
point and the results will be disasterous.

On full frame, the test distance would be 32 meters (40 x focal length). Even more on APS-C, of course. So, not really "close focus" (what's the MFD of this lens?).
