I know there had been threads as to the hollabaloo about the safe trigger voltage for DSLRs and that Pentax hasn't actually made an official statement as to how much trigger voltage the curent Pentax DSLRs can take.
This is exactly the reason why I posted this thread 'coz I had observed that we kept on measuring the trigger voltages of suspect off brand flashes but nobody actually bothered to measure the trigger voltage of these current Pentax flash line-up.
Since most of the safe trigger voltage for the Pentax DSLRs appears to be hearsay, as the 6V is actually for Canon DSLRs and Pentax won't make official statement about how high is safe for Pentax (except for a few unofficial statements ranging from 12V-30V).
Here is a chance to at least measure the trigger voltage of these Pentax flashes and at least have a "loose" guide.
If these flashes are rated to a certain voltage only, then it would be safe to assume or conclude that whatever trigger voltage they come in, would be the safe trigger voltage too if you want to use off brand flashes.
Makes sense?
Now let's see soem figures..
