I hope I will have the chance to take some test shots next week. I expect it will be clean and high-contrast image unlike the conventional lenses. Since the back focus is very limited, mirrorless and one-shot cooled cameras only work for the infinity focus.  Smaller than APS-C format sensors allow to set LPS-D1 and V4 52mm(or 48mm) with a stepping ring, without any spectrum shift issue.

P6080750stmjss7844, 7840(helical focuser for infinity), 7843 and each camera adapter(5013 for Sony E mount) are needed to complete the optical system.
