This is always an interesting, if misleading, discussion that seems to happen over and over. On another board recently there was a lens shoot-off, and by the time I'd stopped reading a number of people had noticed the Fed lens on a Leica was focusing about 4" behind the subject's eyes, even though the picture that was posted for "quality" comparison was tiny--something that others who missed the focus error regarded as "dreamy" quality.
One of the people there who's a constant critic of the critics over there has never, as far as I can see, posted a single photo of his own on that board that was in focus, and I do mean that literally. Obviously lots of people can't tell if something is in focus or not, yet consider themselves experts on the topic.

Others don't care, and that's fine, too, but it's not OK when they call people who do care "too fussy" that their cameras should work as designed and intended. I have three Fed lenses, and a Fed (now out on permanent loan). On my Fed they all focus spot on; on my Leicas they were fine at infinity, but not at 1m, where they all focus about 4" back. It's not Leica's fault, and it's not USSR quality failure, either.
I kept my Kiev. Those lenses are great, and also focus correctly, on the camera they were made for.
