Looking at the E PL-1

[jhelmuth]

I have just got my PT-01 housing and YS-110a for my E-PL1. I tried to use manual flash with the internal flash set to 1/4, only about less than half of the shoots were triggered. I tried 1/16 flash level than none flash could be triggered. Is there anything wrong with my setup?

when I use s-TTL mode with fill-in flash it seemed to be working pretty well though. But I hope that I can reduce the internal flash level a bit to save the battery life.

What optical cable are you using?

Fiber Optics do come in different grades of transmission (in terms of frequency or wavelength and transmission). They also come in differrent diameters.

My thinking is that your cable is insufficent to run at the lower settings...

I'm thinking it is more likely the sensitivity of the S&S strobe or the quality of the cuts at both ends of the cable. Fiber Optic cable is designed to transmit light. I think that losing anything significant along such a short path would be very unusual unless the cable is kinked somewhere.

I'm not in that business - but I'm told that the optical properties do vary widely between different applications and cable grade/quality.

However - regardless of that, I'm in agreement that the finish on the cable end (or possible damage somewhere in the middle) is a real possibility....

PS - In my limited testing, I do find that higher quality optic cable which was made specifically for this application is more reliable.

Thanks for the reply. The cable is the L cable of Sea and Sea, brand new. I use it with S-TTL mode now and it works OK that way. But it just won't work if I set the flash power to 1/4 or less. I did not have enough tests to confirm that when in sTTL mode, when the actual output from build-in flash is less than 1/4 what will actually happen
