Yes, you got the pre-flash bit figured. Cross that off the list.


Thank you.

I tried again. the strobe does not fire with the sync cord connected to the camera but with speedlight off. So, why do I need this cord? Please, help


I never have used an on camera flash, just sync cord or radio triggers, so I am going to have to download the manual for your camera and see if the is a menu item that needs to be set correctly. Don't think so but maybe.

Anybody know about this one?

Thank you so much for your effort to help me. I just don't understand why it's not working. I thought may be sth is wrong with my 6D. So, I tried to do the same thing with my T3i ( connected sync cord from the strobe to the camera. It does not fire. Bit it fires with flash on)

2. when the sync cord is not attached to the camera it still fire simultaneously with the speedlight. Sometimes it doesn't. What is difference if the cord is plugged or not? Does it work through some photo elements?

The strobes have a slave photocell on them. That causes them to fire when the on camera flash fires (as log as the slave cell has a clear view of the on camera flash ).

I checked the 6D manual and the way I read it, if the shutter speed is set to 1/180 or slower, the external 300sdi should fire using the sync cord.
Sorry, I have no way to try this. It works that way on any camera I ever used, but they were all Nikon or Pentax.
Any Canon users please provide the answer to this one!

I set Canon 1/200 iso 100 with speedlight on. The first time I got nicely lit and at the same time very crispy photos of my poor husband who is not allowed out of basement until I figure everything out. LOL.
It still does not fire with sync cord and without speedlight. Still trying to understand.

Thanks a lot. You helped me tremendously.

Just give him the manual and keep him in the basement until it's all worked out.

The camera might be set to use ttl flash control of the on-board flash. Maybe needs to be manual flash mode. (Just guessing.)

Set the shutter speed to 1/180 or slower. The external pc sync may be dissabled above 1/180. (Just another guess.)
Never tried it before but the book says 1/180 so you may not be able to use 1/200 like I told you.

Doesn't solve the riddle but gets around the problem; on ebay you will find little adapters that go on your camera hot-shoe and have a pc sync port. They cost ten or fifteen bucks. But you really shouldn't need to do it that way.

It was a good idea to refer to the camera instruction manual. It says,With large studio flash units, be sure to
test the flash synchronization before shooting with the sync speed set within approx. 1/60 sec. to 1/30 se
c., since the flash duration of such
units is longer than that of compact flash units.

I tried to shoot with fore-said shutter speeds. It didn't help.
The user manual also said, If the camera is used with a flash unit or flash accessory dedicated to another camera brand,the camera may not operate properly and
malfunction may result.
So, I guess the strobe I got may not work with Canon?

I already thought to buy some radio triggers that help to connect camera with strobe. Do I still need speedlight if I have such trigger?
