Is the PC terminal on the K20-D threaded?
Over the years I've had (like most of us, probably) mixed results using PC cables to trigger electronic flash units. I'm interested in experimenting with a screw lock PC connector but need to verify that the K20-D does, in fact, have a threaded terminal to accept this type of connector. It does, to my tired old eyes, look like a threaded socket and the blank-off plug actually threads in and out. I spoke with Lon at Flash Zebra and he is skeptical. I don't have a thread lock connector to test it with and don't want to buy one unless I'm sure that the camera will really accept it.
I'm thinking of rigging up an ORBIS flash ring adapter to my K20-D and an old Sunpak 422. I'd like to trigger this flash off my PC terminal in order to keep the camera's hot shoe available for use with a second flash...perhaps using the hot shoe flash as a bounce for key lighting and the ring flash as a fill.
