Not quite true.  I don't have my copy here, but if I remember Günter
Osterloh correctly from his M book, he delves into this somewhat at length,
comparing the M6 (I believe) to a "typical" SLR (probably an R7) in terms of
focussing accuracy.  The rangefinder was still more accurate at 90mm focal
length, and I think about equal or maybe a tad less at 135mm.  Perhaps
someone with the book at hand could look up the details.
