In my experience, a big part of copywork requires the reproduced image to be true to the original as much as possible. Using software to correct distortion etc. or even perspective is often not acceptable as it affects small details such as text in old manuscripts and so on.
Hence why so much money goes into developing flat-field macro lenses and so much money is spent on buying them...
You should test the HC50 side-by-side with a straight LF lens to tell the difference or just compare a reproduced print to the original.
