How to teach an Old Strobe New trix...??

Hi Light Guru's!

I just brought a otical cable for my old YS 50..and I seem to have a timing problem..

Just tested it a home..and the flash fires..But there is no light on the pic.

The test was made so that there were light from one side so that the Strobe had to fill in the other...and so far I haven't achived this...

What am I doing wrong is the Opical Cable not perfectly in place oer is the old Flash just too slow???

Any help is greatly appriciated..

I assume you've bought a remote sensor for the YS50. The most likely cause of your problem is that your digital camera strobe sends out a pre flash before the main flash and this is triggering the YS50 before the shutter opens.

Solution is if the sensor has an option to ignore the pre flash use it, otherwise I'm not sure there's anything you can do.

HI Ken B!

First of all..Thanks for the quick response...

Well I don't have a remote sensor..but a Otical Cable..

There is NO pre-Flash..as fare as I know & can see(Fuji F31fd)..set on forced flash..??
