There is a big difference, millions of PK/M lenses are still out there with ONLY the cams on them, there is no need to not support those if the cost of support is very cheap in both the body and with respect to the value of the lenses and it certainly is....I am not arguing that new lenses should or shouldn't have mechanical interfaces, I am arguing that these particualar lenses should still be supported that happen to have simple mechanical interfaces. jco

Otherwise every major SLR manufacturer would not have abandoned it (Heck Canon and IIRC Minolta even abandoned mechanical aperture coupling as well). -Adam J. C.
