Just received this information from Pentax USA after an inquiry I sent about Trigger Voltage on the *istDL. I explained that I had measured 195v on an old Pentax flash unit and ask "would the *istDl suffer any damage with that much trigger votage.

This was their answer.

-----------------------------------------------------------------------------------------------------------

"Dear Sir/Madam,

Thank you for contacting Pentax.

The maximum flash trigger voltage on the *ist DL is ~300V. Anything below that
will not harm it.

Not to beat a dead horse, but we really only recommend using a Pentax AF360FGZ
or AF540FGZ with the *ist DL, because you are likely to experience improperly
exposed pictures otherwise. It will not hurt the camera to try your flash, I
just do not think it will work very well. On the other hand, a roll of film is
a lot cheaper than a new flash, so it might be worth testing.

If you are in need of further assistance, please respond to this email or call
our technical support center at 800-877-0155.

Sincerely,
Dorian B.

this isn't even a dedicated flash. well, even if it was, it would not work on the dl.. 195v is a lot and i think i would not use it.. i'd say go to ebay and find a flash but the dl has to have a P-TTL flash to work in autoand there are not many options.. you'll have to use just about everything in manual.. but you can find many flashes w/lower volts on ebay.

alfred(another member) owns a camera shop in the EU. his pentax guy told him not to use anything over 30v. guess you'll have to make a decision..

edit: just read their note to you. it's bad when he says that you might waste a roll of film testing your flash. thought we were talking about the DL...... hmmm

Robar I'm use to using the Pentax ME Super with the SunPak 522 for 30 years. The 522's auto features work pretty well...I'm from the old school, so it doesn't bother me that the new Pentax's features are not all available to me. As forthe trigger voltage, I'll have to think about that aspect and do so more research on the matter before using the 522 with a Hotshoe to PC cord adapter.

Just use a Wein Safe-Sync hot shoe adapter. It reduces the trigger voltage of any flash to a universally safe 6v.
