rf-603 combined w/ 602

I'm using the 603's as a wireless remote shutter release, and on top of the 603 transmitter, i have the 602 transmitter to fire the off camera flash (602 receiver on the flash). getting mixed results

when I trigger the shutter with the 603 remote, the flash fires about a half second late so no light gets in the shot.

When I set the shutter to a 2 second timer or 10 second timer, and trigger the timer w/ the remote, the shutter and flash are in sync. Any idea why this is?

also half depressing the remote 603 doesn't seem to cause the camera to focus like it's advertised to. bad set of 603s possibly?

My understanding is that the 603s aren't backward compatible with the 602s. They don't play well together...

Why do you put the 603 receiver to trigger the camera into it's hot shoe? It won't do anything there, except take up space and be a kludge. Just let it dangle by it's trigger cable.

i've tried that first also thinking that was the case, it won't work unless its on the hotshoe fully. does yours work when its not on the hotshoe and just dangling?

correct, i know you can't use the 603 to trigger the 602 receivers and vis versa, but i placed the 602 transmitter on top of the 603, to trigger the flash I had connected to the 602 receiver. this works, but having some issues as described in op

I am having a little trouble following the set up as verbalized. How are you remotely triggering the camera? I would think that you could use a pair of RF603's to remotely trigger the camera, and a RF602 sitting on the hot shoe to trigger your flash which would have to be connected to a RF 602 RCVR.

yes that is what my setup is, i trigger the shutter with the 603 in the hotshoe, and 602 on top of that. should i be able to trigger the shutter without the 603 on the hotshoe? bc that doesnt work for some reason

I am still a little puzzled. I "Think" you need to connect the RF603 to the Remote Control Terminal of the 5D MK II with a cable. I can not figure out how the camera would trigger with the RF603 sitting on the Hot Shoe. The RF 602 Transmitter should be sitting on the Hot shoe to trigger your flash, which is connected to a RF 602 receiver.

I do not have RF 603 devices, but I own RF602 and have used them to remotely trigger my camera.

603s allow u to mount a flash on top of the transmitter, so u can have an on camera flash while you triggr an off camera flash as well. in my case, im putting a 602 transmitter on top instead of the flash. if u take a look at the 603s youll see what i mean

If you have the 603 in the hot shoe and are using it to trigger the camera you are sending mixed signals.
Its likely the 602 on top of the 603 is seeing the pulse intended to trigger the camera as a pulse to fire the lights. That is what is causing the early flash.
Take the 603 off the hot shoe. Being used as a camera remote release is independent of flash trigger. It is also a fraction of a second before the sync pulse to fire the lights.

They are two completely separate radio links and should not contact one another.

its actually a late flash thats the prob.

ill try the shutter release when its off the hotshoe again. it def shoul work?

The way I use the triggers to remotely activate the camera is through the Remote Control Terminal on the body. I am puzzled as to how the RF603 sitting on the Hot Shoe would be able to trigger the camera.

i def have the wire connecting it onto the remote control terminal on the body, but when i let it just hang, it didnt work. i had to mount it on the hotshoe which i found odd since i've read that you don't need to mount it. maybe dangling it caused the connection to come loose. i'll try again tnite with it off the hotshoe

still no joy, can someone who has the 603s confirm they can use the wireless shutter remote without mounting it onto the hotshoe? mine will not trigger unless i have the 603 transmitter on the hotshoe.

also learned that it will only focuse when in automatic mode, won't focus with the trigger half depressed in M mode. if anyone else can, pls let me know so i can dispute w/ the seller.

I do not have RF603's to help you out. If you have a RF602 Tx and RX pair, you can use that to remotely trigger the camera to verify that the function in the camera is working.
