Support commonly-available threaded couplers for PC sync connection

The PC sync port on Pentax dSLRs, while threaded to accept a cap, uses a proprietary thread, making finding replacement caps difficult and locked mating to available screw-lock PC connectors impossible. It is my understanding that the screw-lock PC port originated with Nikon, but has since be incorporated on many other brands such that Nikon, Canon, Olympus, Fuji, and Sony are able to use the same type threaded PC connectors. It would be nice if Pentax were to join the club.

Every once in awhile we get questions/rants why the threads for the PC fitting don't work with generic thread-lock PC cables. The particular problem is that PC cables tend to pull out with little provocation, a historic problem dating back to the invention of the fitting type.* One can use gaffer's tape to secure the cable to the camera, but since Ricoh/Pentax already cuts threads, wouldn't it be nice to make those threads the same as those used by flash/cable makers?

Of course, there is also the problem of replacing lost/misplaced covers. The part is generally unavailable from Pentax with no generic equivalents.

* Even back in the 1950s, camera makers were providing retention collars to work with proprietary cables. I have several bodies featuring such.
