I have found that when my focusing starts to slip, the problem has
nothing to do with the rangefinder. Rather, my glasses invariably need
replacing. ;-)

i like konerman's steer on my noctilux very much, i've mounted it also
on the 75 lux and 90 cron ASPH.  to further improve the odds of getting
good focus on a lens which has about an inch depth of field 
at 5 feet, i also like the 0.85 viewfinders, or M3s, and
the 1.25 eyepeice magnifier.

i have had to send in both my M6's for rangefinder adjustment, i once
had to send in a 90 cron because its focus was out of adjustment, and my
M3 after a shipping mishap was also off-focus.  the MP has been fine so
far.  i have never had to "match"  focus to a specific lens; i think
that an M adjusted to specifications with an M lens also in spec should
be able to consistently focus within that len's 
depth of field.

some degree of delicacy seems to be the nature of rangefinders; i have
had to 
have my super technika's rangefinder adjusted, as well as fujica GS645
and contax T.

i tend to periodically shoot a tape measure on PanF focused at 6 feet 
on the tape when i notice my focusing isn't quite right and always when 
acquiring a new rangefinder.  put the camera on a tripod, open the lens
up all the way, use a cable release and shoot 3 exposures, racking focus

to infinity and then refocusing between each exposure.  it seems tedious
but it really only takes 5 minutes and 3 exposures, and gives you
confidence that your system can focus accurately and consistently.
