I forgot to mention, the reason I brought this up is I just got an essentially NOS Auto Mamiya/Sekor SX 105mm F2.8 (M42) lens and had a hell of time getting the surfaces really clean. Chaulk this one up as in the "difficult to clean coatings" category. Awesome little lens BTW. Haven't had the time to get out and try it and now the weather has gone rainy for three days....
I know the build quality isnt up to Pentax Takumar standards, but these Mamiya SX lenses are great performers and very inexpensive on ebay usually ( not in this case, as its a rare focal length and the bidding got up there ). The only caveat is they dont have manual mode switches so you cant use them on K bodies unless you are willing to do something like superglue the aperture actuator pin in place and make them pure manual aperture lenses forever.
