Multiflash on Canon 6d

[1635blue]

Hey,
I recently bought the canon 6d, i have (3) speed lights ex and i want to connect them to fire at the same time.
Before i had canon  7d and it was easy with the internal flash.

Have you considered getting a radio trigger system?  Phottix is good.  Pocket Wizard too.  It is extra money, but it works better than the old flash-triggered system, and over a lot longer range.

thank you for you answer

I will try to get the radio trigger system.
So there is no other solution, like put a speed light on camera and manage it to send signal to the other speed light to fire at the same time when i take the picture?

Are these Canon brand speedlites or are they 3rd party flashes?

If these are Canon brand speedlites then you can use a Canon 90EX on-camera flash which is capable of operating as an on-camera "master".  It's not a particularly powerful flash but if you're just looking for something to replace the pop-up flash you had on your last camera, it is able to perform that role.

The Canon 600EX-RT (Canon's flagship flash) is able to perform any role (optical or radio... on camera master or off-camera slave.)

I have a couple of 600EX-RTs and a Canon ST-E3-RT (on-camera radio trigger) and I love the reliability of the system.

I've had really great experiences with PocketWizard Plus III units. 

If you're trying to work on a budget, there are a lot of aftermarket flashes with optical slave functions. As long as you're the only flash shooter there, and you're not using multiple preflashes, and you don't mind manual everything, they get the job done.
