Is the question you're waiting for about the voltage for the D80 and can I use that lead with my flash guns? I know that the "Topca 325b!" has got a very high voltage output and I take it, If it's to high for the D80 I won't even be able to use it with the SC-28 lead?

Lello,

In short any flash with a high trigger voltage cannot be connected safely to ANY electronic camera by whatever means.

When I get a moment I will take the front off an old mechanical camera so you can see the lump of copper that is the flash contact.

I have downloaded the D80 manual but have not had a read through yet to see if there is a specified max trigger voltage. With the D100 I did a test, and the pop up does do a preflash whereas my SB80 trips my remote guns fine when used with SC-17 lead.

It is still possible that your Yinyan cy32twz will be fine with the lead. Do you know its trigger voltage off the top of your head ?

Lello;

You did not pay attention to the second part of my reply. Just turn off the D80's (When you get it, hopefully in mater of days), flash. Use a off camera hotshoe flash sync cable (These are cheap and last a life of useful service including macro etc). Use a cheap and not a TTL flash on this (If cable is TTL, that hopefully is for other situations). Now everything is manual and your other flashes will fire perfectly with the first shutter curtain, so no problem what so ever.

Christine's partially dampening the pre flash light is also smart. However due to under exposed reading of light, your on camera's flash will probably shot at max out put that if right for the given situation, should cause no harm or other wise you may over expose by fire of this flash.

Its great to have Don here. My endless solute.

The Yinyan was sold as a flash unit for the FZ30 (because of the voltage output) so it must be at very most 24 volts. I will see if I can find the paperwork for the yinyan to see if the trigger voltage is mentioned

Can you explain TTL, in layman's term?

Very similar to the TTL (Through the lens) sensor for general light measurement, the newer cameras have TTL capability for flash light measurement. So either the flash out put is measured that way on auto TTL mode or that pre flash, flash could help in this kind of measurement apart from probable focusing assistant as the case may be. So if your external flash is a dedicated, TTL one, a TTL cable (The hot shoe has several pins instead of only one single central pin for manual ones), it still can exhibit that pre shutter release flash, therefore firing and discharging all other remote flashes on the slave.

[sassan]

Oh another bypass is to use wireless (Radio wave) trigger and slave. Needless to say this is expensive, power hungry and not my kind of stuff.

Lello,

I must watch ' Planet Earth ' too much wonderful filming of nature. If Sassan does not answer I will be back later.

Don enjoy the show if you can.

So when I finally buy the D80 (in the new year now) is it worth investing in a TTL flash unit or will what I have be alright to keep me going for a while.
PS with the Dollar against the Pound it might worth me coming over the pond to buy a D80 over there
