Does anyone know if this flash unit will work on the FZ20?

Here is a link that has trigger voltages and how to check the voltage yourself.

http://www.botzilla.com/photo/strobeVolts.html

The FZ cameras can use up to 24 volts and no more.

It says on the site that all speedlights are 12 volt but you would do better to check it first.

Yes it should work.

I've been using my SB28-DX on it for awhile. Worked great. THen I got a slave unit "Nikon SU-4", work even better.

Thanks. It uses 4 AA batteries, so it must be only 6V

the battery voltage is nothing to do with it.

It is the voltage created by the flash circuitry - which can be substancially higher.

Some flashes using just 4 AA batteries can generate a trigger voltage of hundreds of volts, which will gradually fry the circuitry in a modern camera

As it is, the SB20 is fine, as that has been tested at 5.5v

I have a Wein adapter which fits into the hot shoe of the FZ20/10 and the flash slides into the adapter, it regulates the voltage so as not to exceed 6volts. I use it for my strobe system as it has a pc sync cord outlet as well. It cost me 540 at B&H photo.

Hey genece, thanks for your post regarding trigger voltage. I am planning on buying the FZ20 right after Christmas and I e-mailed Panasonic a few days ago and asked them about trigger voltage,but so far, no reply. I have a 5 year old Vivitar 285HV that I was hoping to use with the camera. Thanks to your post, I see thatthe 285HVis factory rated at 12volts for the trigger voltage. By not having to buy a new flash, I can put the money towards memory, batteries, filters,...etc. My question to you is are you SURE that the FZ20 is indeed rated for up to 24 volts? Not meaning to doubt ya, but I do wanna be sure. Thanks again for your informative post!

Yes it is in the manual under the External flash section on page 82 of my book, it states any flash (less than 24 Volts) will work.
