Dan Lau <dlau@xxxxxxxxxxxxxxxx> mistakes numbering for 24/2.8's with that for
28/2.8's and writes....

   In response to whoever keeps the "serial number to MC correlation" database,
   I've deleted your message, but I have a 28/2.8 with a serial number in the
   1406xx range that is labelled "Zuiko MC".  I purchased this lens from
   someone on this list last year (sorry, memory ain't what it used to be).
   So it appears that there is a batch of 28/2.8 lenses with the low serial
   number that are MC after all.
      -Dan

Since my interest is figuring out what a lens is from from photos on ebay... I
collect both serial numbers and markings and have been adding to Paul Schings' (
Pauls0627@xxxxxxx) list...  From this one start's to figure that the 28/2.8
which is said to have always been mulicoated (
http://www.datasync.com/~farrar/zuiko.html - But I always wondered how Paul F
knows... )  And assuming that the lenses tend to start with 100000 it looks like
the 28/2.8 probably started as ZUIKO MC while the 24/2.8 started as an H.ZUIKO
single coat  and went through ZUIKO MC to finally just Zuiko  (anybody care to
share what the exact Zuiko MC 24/2.8 markings are?)  And aren't you glad I've
held off on replying to the (I presume) rhetorical "what were the 5 flavors of
50/1.8?"  (psst... stick to the ones labeled "made in Japan"! ;-)


<< the demented one crawls back to his den of Zuikoholia and but leaving strange
markings on the inside of your computer screen... fungus? or a lens list?>

 24      2.8      220220 Black   MC  No   ZUIKO AUTO-W 24mm 1:2,8 sn Japan

sn == serial number, if on the front ring (some lenses, especially those late
50/1.8's have the sn on the lens mount)
note: some of these sn's end in 0 because I'm paranoid with other peoples stuff.
