BTW: If you are looking for 40 IF level performance, you may want to consider the Distagon 3,5/35 on Contax 645 + digital back as an excellent performer. This lens has internal focussing (IF) and MFT charts look similar to the 40 IF. My guess is that those two lenses are based on the same design, but the 35 is to be had at a fraction of the cost. Of course, CONTAX as a brand no longer exists...
