K100D trigger voltage toleration?

uPiX · 07-26-2007, 01:14 PM

Hello

I just got my very first DSLR on tuesday and now I try learn how to use it.

Question is that my father has an old National PE-387S external flash and I tried does it still works and I managed to fire it attached on the camera. Then my friend told me that old flashes could have high trigger voltage that could burn circuits in new digital cameras. I searched in the forums and someone said that K100D could handle 30V trigger voltage. Is that right? I measured that this PE-387S has 8V trigger voltage and site for trigger voltages (link I found in forums) said 7,8V. So is it possible that I have already burned circuits in my camera or can I continue using this old flash?

Thanks

Pentax USA quoted me 25v for the K series DSLRs. If your measuring only 8v, you should be fine.

OK, thanks.

I asked from Pentax Finland and they haven't answer anything yet.
