Help! Sync problem between 300D and strobe

[oaynuj]

I've a 300D + 3x Elinchrome 500 strobes
problem is using the built in optical trigger sensor on the strobes n the pop up flash as the trigger the strobes fire too early n the shot comes out only with the pop up flash. Tried it with a speedlite 380ex, same results.

Works fine with a nikon F90 though. Trigger voltage for the strobes r 12V. Anyone has any idea if it's safe to use sync cords with the 300D and where i can get the hotshoe converter.

thanks in advance

that's the problem with E-TTL. The speedlite unit gives a pre-flash to determine the correct amount of flash power for exposure. the pre-flash triggered the strobes.

hotshoe sync connectors can be bought at Cathay Photo, MS Color. Should be no problem with sync cords.

another alternative is to get a cheap small manual flash unit. can get from Ruby at Peninsula Shopping Centre.

fixed it liao...yaay
i feel dumb though haha~
Thanx again pple

Found 2 methods:

1)taped up 2 contacts on the 300D to turn the 380EX into a fully manual unit (damn powerful, shall cover w cardboard)

2)use FEL with pop up flash, wait for strobes to recharge then shoot (annoying but works)
