Hello...

Would the Olympus T-20 flash unit be SAFE to use on an E-1 and will it work?


I would prefer to get a FL-20 (as price is cheaper) than the suggested FL-36, but I need to know has anyone every tried it?

If it is a case the E-1's hotshoe design matches the E-10/E-20, perhaps someone's used it on either of those models?

Also, I've spoken with a few people and the Sigma EF-430 (I own), measures at: trbigger voltage- +4.70 vdc. That's under the 'safe' + 6vdc range.

If I had to even tape over (or block the other control pins), just using the center contact pin and the GND rail contact, would that hurt the E-1?

I've got my (used-but "new") to me ;-), E-1 enroute shipping, so I can't test it (but will need flash).
Thanks for your time....
God Bless,
Ed~ (ELS)

it is considered a questionable call

5-7.4V as it charged, measured by Brian Zimmerman,
only 2.6v from Greg Clark

it does depend what the safe voltage is for E300
im sorry but i dont know what that is

All blocking the pins will do is defeat any TTL capability, not cut voltage. You can measure the trigger voltage with a simple multimeter (see your local Radio Shack). The positive (RED) lead to the hot-shoe pin on the flash, the minus (BLACK) to the metal strip on the side of the flashes hot-shoe foot (by the wheel which screws it onto the camera). When in doubt you can use what's called a Wein-Safe unit (around $50 USD from B&H Photo or other suppliers) that goes between the flash and the camera's hot shoe. It reduces trigger voltages to the safe 6V level (and also will defeat any TTL control).
