Need help with Yongnuo RF-603 transceivers

If you initiate a trip of a shutter and an electronic flash at the same time you will NOT capture the flash exposure.

It takes a meaningful part of a second to get a shutter to open. Electronic flash is almost instantaneous.

So, if both the shutter and the electronic flash are activated at the same time the flash burst will be over before the shutter actually opens.

Place one 603 on the camera's hotshoe and set it to channel "X", place a 603 on a flash unit and set that 603 also to channel "X".

Run a shutter cord from another 603 and connect this to your camera's shutter port. Set this to channel "Y". Place a 603 in your had and set that unit to channel "Y".

Two independent sets of 603's. One for the flash, one for the shutter.

Report of this methodology works.

Enjoy! Lon

This is how I thought I needed to set everything up to make it work, but I was able to get it to work how I described in an earlier post.

1 603 on each flash unit, one in the camera hot shoe with the shutter release cable connected, and the 4th 603 in my hand as the remote. All set to the same channel. Everything worked as it should. The shutter released and the flashes popped. No cut-off and no dark frames.

This was on a 60D if it matters. No custom functions set other than back-button focusing.

I'll set it all up again when I get home from work and report my results.

Wow. I forgot all about this thread.

So, I set up my camera exactly how I describe above, click the button on the 603 I'm holding, and everything works perfectly. I get a shutter release and flash pops. I really don't know why this setup is not working for anyone else.

Works fine for me in this method also. Using a 60D, 4 RF-603 units, a Yongnuo YN-468-II and YN-460-II. Both flashes in Manual mode. All 4 RF-603s on the same channel.
