I don't have a voltmeter and Hi Mishka, in the most recent Sunpak catalogue, there is no mention of the 522, (it's a handlemount isn't it), there is only 622/622Super (which is the biggerst one with interchangeable flash heads), 555 (which does ttl), and 544 (no ttl). I had the european version of 555 (G4500DX) and it had TTL and low voltage enough (under 6 volts IIRC), so your 522 could be safe. You can see for yourself it its TTL or not - all TTL handlemounts have a two-row 8-pin (? iirc) connector most probably on the underside of the flash head. To this you connect the ttl cable which is connected to a ttl module on the camera. The cable is Ext-11 for the handlemounts. Good light, Frantisek Vlcek

My Sunpak flashes are < 7 volts so that should not be a problem. I am not sure about TTL, but IIRC it doesn't.

Re: Flash trigger voltage & Pentax cameras
Anyone knows if Sunpak 522 can fry LX? I don't have a voltmeter and not willing to experiment... And if those two can work together peacefully, does it do TTL with LX?

> How and with what do you measure > [flash voltages].?? Simple, put your tongue on the trigger and shoe spring (you may have to suck), charge up the flash and then guess the voltage before you pass out. :-) OK - Not really. I just hung a multimeter over the two terminals once the flash was charged.

This voltage is present on the contacts of the flash when the flash is on and energized. IIRC, the camera dead-shorts these contacts to trigger the flash.

Re: Flash trigger voltage & Pentax cameras
Simon, FWIW I have an older Achiever flash (don't remember the model), GN is 28/meters and I always used it on my Program A (Program +) without problems. This unit must be at least 15 yrs. old. If you're interested I can dig it out and check the model. Ciao, Flavio
Re: Flash trigger voltage & Pentax cameras
I cannot answer your question Simon,but have one for you.How and with what do you measure these amounts.?? Dave Begin Original Message From: Simon King <[EMAIL PROTECTED]> Sent: Tue, 27 Aug 2002 07:53:07 +0800 To: "'[EMAIL PROTECTED]'" Subject: Flash trigger voltage & Pentax cameras Hi All, On the weekend I bought a flash (Achiever 821TZ) on impulse as I thought I could use it as a backup and/or a slave flash. I thought I'd check the trigger voltage before I put it on either of my cameras (a Program A and a MZ-6/ZX-L) When I checked it was 270v! I was amazed! On my other flash it's only about 4v. There's no way I'm putting it on my MZ-6, but my question is - would the Program A handle the hight voltage? I note that the manual states that flash units from other manufacturers "may damage the electronic systems of your camera" ... At 270v I wouldn't be surprised.
