Remote release and Live View used to ensure sharpness. Multiple aperture series were shot and checked; the one shown is the very best result. The point to be taken is that focus accuracy is more important than anything else to lens performance!

Images processed in Canon DPP at Standard to 16-bit TIF, Smart Sharpen {100, 0.2, 0} , Levels {8, 1.0, 230} to add contrast.
