Optical sensor on 580ex

Hi guys,

I have a problem. And i think for you specialists this must be piece of cake. After reading the topics on model photography, and admiring all those very nice shots i wanted to try myself. So i hang a black fabric in the pool, and shot with my canon 500d, and a single ds160. Pictures weren't bad, but not as those i saw here. I decided to place a flash on the topside, for lighting the hair. I have a canon 580ex flash, so i wanted to use that. I bought an hama optical sensor for the flash, so i thought it would fire every time i let my ds160 fire. Now that's the problem. No matter what, if i put the 580ex in none, master or slave, it flashes once, and then i have to reset the flash for another shot... What am i doing wrong?

Some general info: i don't know as much as most members here about this: the ds160 is connected trough the ttl cable to my housing. How do all of you manage to fire multiple flashes on topside?

thanks in advance for the info !!

Hello and welcome.

I too have a flash sensor for my 580 (optical trigger).

Firstly, you have to disable the TTL on your housing - so that your DS160 is not firing any preflash. That preflash will mess up the 580.

My ds160 never gives preflash. Either way, the problem is that my 580 only fires 1 time. For the next picture, i need to switch the 580 off/on again...

The trigger voltage may be too high from the trigger. This will cause the flash to need to be reset. You can use a Wein Safesync or other to help w/ that.

I have also emailed to hama. This is their answer:

thank you for the email.

The Synchromat isnt intended to work with canon 580ex flashes together.

At the backside of the original package of the product we described

"not for Canon 199A,244T,277T,300TL". That also means that it dosnt work

with current flashes out of the canon productline.

We have the synchromat over 10 years at our productline and at the very first time

there were only the flashes available which are named before. We dont change

the label of the package for years. There was no reason to do this, because it is logic

if the canon 300tl dosnt work with the sysnchromat the newer flashes of canon doesnt too.

I Ihope this information was helpfull to you.

Best regads!
