Mark, I think that would be the Super Takumars and earlier screwmount lenses. I believe all the Pentax K mounts and later are coated on both sides, EXCEPT for the Takumar (not Pentax) brand. That is the Takumar K28/2.8, Takumar A28/2.8, Takumar K135/2.5, Takumar K135/2.8, and a number of zooms. Check here under Non-SMC zooms. http://www.bdimitrov.de/kmp/lenses/index.html#data Regards, Bob S.
