Hi All,

I have a Pentax K100D and my old nissin 2800G (which i believe is thyristor based?).

Pentax (as all manufacturersdo) specify only to use their own flashes.

my question is: will the Nissin work with the K100D, or will it fry my camera? I'm conerned that the voltage may be too high for it.

Please be gentle, I'm a newbie.

Hi bbb,

Welcome to the forum!

It looks as if the Nissin 2800G has a very high (137V) trigger voltage.

Here's a link that's a pretty good resource, but realize that the information has been gathered from unknown sources, so might not be correct.

I believe that there are also instructions if you want to test it yourself. If you don't have a VOM, you could try taking it to a local electronics store -- they'd probably be willing to test it for you.

It's pretty much a consensus that the K model Pentax DSLRs need less than a 6V trigger voltage to be safe, so you were wise to ask before trying it.

Sorry, one more thing please Scott.

Where did you get the info (voltage) on the Nissin? I've tried everywhere, can't find anything.
