[KOML] Series filters AGAIN!

[jlaird@juno.com]

Hi all,
  Recently I queried the group about series filters for the 90mm and got
some invaluable advice. Thanks again for all the help. I took my 90mm in
for a CLA which, BTW, it needed dearly, and had the series adapter
removed. I now use 49mm filters with aplomb any time I need them ( which
is pretty much all the time, as I don't own a lens cap). 
  My 180mm is sans adapter and accepts 67mm filters. Does the 59mm (which
I don't as yet own but plan to get) also have a removeable adapter ring?
I'ts listed in the owner's manual as a Series 7, but then the 180 is
listed as Series 8!
  Thanks again for your help.

Jim
