> KFA is for SFX etc It seems as if the two of you are referring to two different systems of nomenclature here. The "A", "F", "FA" (etc.) names are taken from the markings on the lenses (and the MEF's one dedicated lens was referred to by Pentax as an "AF" lens), while the "KF", "KA", "KAF", "KAF2", "KA2" (etc.) names are the nomenclature to refer to the K-mount details. See Table 1 (and also Figure 1) on Boz's (extremely useful - Thanks once again, Boz!) web site at http://www.bdimitrov.de/kmp/technology/summary/index.html . Just as an aside, I believe that the only name used in the "A", "F", "FA" (etc.) system of nomenclature that was ~not~ taken from the designation embossed on the lens is the "K" name (where Pentax simply referred to "SMC" on its pre-"M" lenses).
