Yesterday I tested a Canon 5DII with the 17ts and a SINAR ARTEC with the 23mm from Rodenstock and the Emotion 75LV.
Here are the results:

on the small images you can`t see all details, but the Emotion Back is clear better.
But only printing bigger than DIN A3 (11,4x16,5 inch) you can see the difference, and there is no book larger than this size...
By the way, I was quicker with the SINAR, leveling is easier.....
