Hi! Welcome to the Pentax forums!
As to whether it is 2.5mm or 3.5mm, the easiest way to find out is to simple look at the fitting on the camera body. It is 2.5mm. What is more difficult is to determine the number of conductors. I just went to the B&H Photo Web site and entered "pentax cable release" as a search term for that site.* The search returned 12 items including some where the plug is readily visible.
The plug is a 2.5mm/3 conductor (stereo 2 ring).
I agree that the camera documentation is not very helpful in regards to the use of a wired remote. There are multiple situations where
the wireless remote built-in IR wireless remote may not be the best solution. I hope this information is helpful and sets you on your way.
