Oh, one other thing.  If you think that new lenses do not have dust and crap
in them, try shining a torch through the thin end and look through the fat
end.  You will never worry about dust specks again!  I bough a Noctilux over
a year ago and made the mistake of doing just this.  Did it with the 90 APO
as well and it is not a pretty sight but the lenses are optically perfect.
