Help!

I've looked through both camera manuals and the only thing I can find on flash sync voltage limitation is for the E-1 that says "250V might damage the camera".

So before I fry my brace of cameras does anyone know what the max sync voltage is for them?

The new lights I've just bought have a 6V dc sync voltage.

Many thanks in advance of any help and advice given.

Good question.

All I can add is that I use my SB28 (6v) and a Sunpak 433 (7v) with no problems at all.

tough one - you really need it from Olympus 'officially' given the risk!

fwiw my understanding is that below 250 should be OK with the 3 but I have declined to use my Sunpack with it's 220v

whilst I wouldn't hesitate with 6v I couldn't reference anything that says '6v is OK on an E30...'

Most Olympus's have a 11 volt max on the hot shoe and 240 volt on the Pc Socket. Canon is half that at 5.5 v on the hot shoe. ;)

See this thread (http://e-group.uk.net/forum/showthread.php?t=6648&highlight=voltage)..

"I know this subject has come up a few times; so I decided to ask a contact at Olympus Japan for a definitive answer on the voltage limit for switching non-dedicated flash units, both via the hot shoe and via a PC Sync cord, where this is provided. The answer is, for Olympus E-System bodies, and both hot shoe and PC Sync connections, a limit of 250V."

I use various old flashguns, off camera and on, including some vivitar 283s at 200v.

IIRC the E-1 (and E-3.... et al) is designed to work with a 5V sync. So it will work fine off the 6V from your lights. I use Bowens GM400 strobes and they have 5V on the sync connector, the FL50 has 4.8V (measured on mine).

Some strobes put out a higher voltage and the 250v will certainly fry your E-1. I think 5v is a standard and if you stick to it you will be OK. The extra 1V from your lights is within the tolerance.

Hi I have used my vivitar 283 at about 250 volts on my E1 with no problem , although i did not realise at the time there was a contact voltage limit on some digital cameras so i was lucky i just used my film equipment i had in the bag from long ago still looking for my bellows.:)

Many thanks for the helpful input from everybody.

As per one of the recommendations I have e-mailed Oly since
their FAQ system didn't yield any info.

I'll let you know what the answer is once I get my reply.

Terry,

I am not sure what your concerns are.

The sync voltage of your lights is only 6v, which means it couldn't be much lower. I could understand your concerns if your lights had a 250v sync voltage. You cannot do any harm at all with your lights. The E-1 is perfectly OK with this value.

I enquired with Olympus via a contact in Japan and he confirmed that 250V is the acceptable limit for E-System cameras.

I'm relying on that information source, so please don't hold me responsible if anything goes wrong, but I can't see why ther would be a problem based on the source and the information.

Steve,

Ignorance I guess, and the experience a friend had of frying his
camera circuits. Unfortunately I can't remember what camera and what voltage was concerned but he definitely was very unhappy.

Since the members of this group are so knowledgeable I thought I'd check just to be safe and assured.

And Ian, very many thanks for the reference to your japanese contact's information.

As promised, here is the reply I received this morning from Olympus Europa, Prague Office.

"Hello

Thank you for your query.

Maximum trigger voltage for both models (E-1, E-30) is 250V.

Kind regards

Ian, your contact in Japan was correct and his info is now confirmed officially.
