I agree with John, I don't feel old technology was taken much into account with the ist D, even the use of manual aperture lenses was an afterthought. Nor do I feel it really qualifies as "Pro Level". I did just notice however that the Vivitar 283 and 285hv are still in production, that's amazing in this industry. Perhaps they are OK for new cameras, I wouldn't think they'd still be this popular if they were in the habit of blowing things up. ;-)
Another point of interest, every Pentax camera I've ever had apart uses exactly the same circuit for the hotshoe and the PC socket. It's just a wire from one to the other. This includes the MZ/ZX-5n. John, by your post below you seem to be indicating that one is different from the other in some way. Do you know if some are a different circuit, such as the MZ-S or PZ series, neither of which I've ever had apart?
