The A/R would indicate that it's a Ricoh as well as Pentax A mount compatible. I've got an CPC 2x adapter, (made by Pentax according to Boz's site), which seems to work fine on my MZ-3 and ZX-5n, (well electronically at least, the optics are a different story), but never worked correctly on either *ist-D or Ds. I believe that the R(icoh), part of the specification probably breaks the A protocol as far as the DSLRs are concerned. I just learned to live with it, (not like I use it much). Hell, I paid $3.00 for that particular converter so I guess I can't complain much.
