That's exactly the way mine is--well I don't know if it will make 10 meters. A cursorary glance at a full size image and you might think it's OK, but if you look close the lens is not sharp at long infinity (meaning my lens), while the CZJ 50/1.5 is quite sharp in the centers at the same range.
However at portrait range my copy is superb, with excellent sharpness.
Dante Stella mentions this, but in regard to wide open performance.

now same day same place, canon ltm 50/1.4
this is APS-C with amedeo adapter. I can't think how amedeo adapter would effect anything but RF focus--but please correct me.
