And then to complicate matters even further, theres the Takumar (non-coated) K mount lenses... http://kmp.bdimitrov.de/lenses/primes/_non-SMC/tak_28f2.8.html http://kmp.bdimitrov.de/lenses/primes/_non-SMC/tak-A_28f2.8.html I have one of the first ones I picked up in an auction lot some time back, I've never used it though. As far as I can tell both of these are similar optically to the 'A' lens or later of the 'M' series, sans the coatings of course. - Peter -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
