At one time I had posted a picture from the test but it's down now. I photographed a ruler at f/2 from 1 meter, and the point I focused on was the sharpest point in the photo. Not scientific, but my experience in actual use has borne it out. I haven't shot anything at infinity and f/2 but have seen no indications of a problem with distance focusing in day-to-day shooting. Karen Nakamura says you can determine the year of manufacture on a J8 by the first two digits of the serial number. If she's right, mine was made in 2002 so it's a late model. Maybe the later ones didn't have the problem. I've also used my J8 on a IIIc and M6 with no apparent focus issues. But other people have reported problems like you describe. I understand it's easy to fix, but then it wouldn't be right for the Zorki, I guess. Phil Swango http://pswango.smugmug.com/
