Hmmm, <looks at camera>.  Pentax *iST DS here.  I can see it is a coaxial 
socket, but my impression is the bore is too small for a 2.5mm jack. 
Squinting into it with a magnifying glass, I think I can make out sleeve, 
ring and tip contacts.  I think I have some in my old electronics junk box, 
so it won't be too hard to check.
